I need help with an area and width question!! Please help!!
I might be able to help what is it?
I am not very good at math though
I will type in the first part! Mike want to build a rectangular garden box with a total area of 250 square feet. If the length is 25 feet what must be the width? a)Write an equation that shows the relation between the relation of the numbers using w as the variable for width.
@dan815-will you look at this too?!
Well i think you do 25w = 250. but i am not 100% positive
@pooja195-- would you also look!?
Is that your answer for (a)--the second part of this!?
beyonced98--do you know this??
thats my answer for a, but i dont know if its right what is part b?
solve for w
well i think then you would just divide 250/25=10. but that would only cover length and width not height.
@ganeshie8 will you look at this please??
@TheSmartOne will you please help!!???
I will post the question again
Mike want to build a rectangular garden box with a total area of 250 square feet. If the length is 25 feet what must be the width?
@darkbeautystar how do you find area of a rectangle?
you multiply the perimeter on 2 of the sides
please help Nnesha- i really dont understand
I really just need help
Area = Length * Width
Seems like Ganeshie has come to the rescue, no need for me anymore :P
He is offline
Ok Area = length x width area = 250 length = 25 So 250 = 25 x width can you solve for width?
i can try
w=10ft
correct, so that's your width :)
thanks
then what would be this q- Write an equation that shows the relation between the relation of the numbers using w as the variable for width.
I have this q with (a)-(d)
i just feel the earthquake on this post
so pretty much 4 qs about the same thing
What??
I just need help with these 2 questions (a)--Write an equation that shows the relation between the relation of the numbers using w as the variable for width. <----don't know what this means (b)--solve for length in a garden box where the area is 100 square feet and the width is 12.5 feet <---- not sure what to do
please help
for (a), I think they want you to write length*width= area and fill in the numbers for length and area, to get 25w = 250
thanks- do you know for b
for (b), first write down the formula for finding the area of a rectangle.
so w*l=a
@phi
@DatChinookGuy
I just need help with (b) now phi
** so w*l=a*** yes now replace the letters you have numbers for. they tell you for question (b) area is 100 square feet and the width is 12.5 feet do you know how to do that ?
not really--could you teach me
well actually yes i think so-- 100*12.5=a
in w*l= a w is short for "width". if you know the width is 12.5, then you can erase the "w" and put in 12.5 instead
ya i know
was my equation right
**well actually yes i think so-- 100*12.5=a*** that is close but remember the "a" is area. you replace the "L" (the length) try again
100*a=12.5 or 100*12.5=l
start with w*L= A now replace the w with 12.5 replace the A with 100 leave the L alone
12.5*100=l
no, go slower. w*L= A first, erase the w, and put in 12.5 what do you get ?
you get 12.5*L= A now erase the A, and put in 100 instead what do you get ?
100
I dont get it
do you understand we start with this formula w*L= A ? that is how you find area. It "says" width times length is area if we had a number for width, we can replace the letter w with its number In problem (b), they say width is 12.5 so the first step is replace the w with 12.5 in w*L=A can you do that ?
yes--12.5*l=a
the "w" is a place holder to remind you where to put the width (as a number)
yes, that is good 12.5*L= a (I am using L instead of l, because little l looks too much like one 1 ) next, problem (b) says the area is 100 in 12.5*L=a which letter stands for area ?
yes i know that
a
so if you know the area is 100 where do you put the 100 in 12.5*L= a ?
12.5*L=100
yes, and that is the answer for (b) you can also write it 12.5L= 100 because when we multiply a number times a letter, people don't bother to show the multiply sign.
thankyou so much- thanks for being pateint. I have more questions about different math questions but if you dont want to help you dont have to. there are only 2
wait! -solve for length in a garden box so we have to find what number L is to do that, we start with 12.5 L = 100 and divide both sides by 12.5 \[ \frac{12.5}{12.5}L= \frac{100}{12.5} \]
on the left side, 12.5/12.5 is 1 so the left side becomes 1*L and that is L what do you get for the right side?
1? I dont really know
can you do 100 / 12.5 ? divide 12.5 into 100 you can use a calculator?
Yes
8
so here is what you did start with 12.5L= 100 divide both sides by 12.5 \[ \frac{12.5}{12.5}L= \frac{100}{12.5} \] simplify both sides \[ 1\cdot L = 8 \\ L= 8 \]
so is that the answer??
:/
yes. length is 8
so i just put l=8 ?
L=8
yes. But they may want you to show the work, which is posted up above.
ok--do you want to help with 2 more. or not
@phi
what is c) ?
c is solve for w- which i answered 10ft
what is the next question?
that is it for that question- but there are 2 totally different questions
which is what i tried to tell you- im sorry- i guess you didnt get that
can you make a new post, please ?
ya
