Question

a picture frame is shaped like a rectangle whose perimeter is 182 cm. the length is 6 times as long as the width. find the length and the width

Answer 1

no i dont and i think that is where i am getting all confused

Answer 2

The FORMULA is a rule you must memorize!
I'll show you how to plug in after you find the formula yourself :)

Answer 3

ok the one i have is p=418 L(10w) find Land W
p=2L + 2W

Answer 4

418=2(10W)+2W

Answer 5

w=21
l=210

Answer 6

2(20)+2(21)=418

Answer 7

had to do a whole new problem cause after i entered it wrong three times i had to do a similar one and its like my 8th time.. i have three questions all kinda like this

Answer 8

That's why you need to back track to the formula now :/

Answer 9

2( W + L ) = P

Answer 10

-> W + L = P/2

Answer 11

@nmoore Understand up to here?

Answer 12

width plus length = p square?

Answer 13

oh ok

Answer 14

Now, can you plug the numbers in ?

Answer 15

the length is x the width
perimeter is 418

Answer 16

DIVIDE the perimeter by 2, NOT squared, NOT multiply !!!

Answer 17

418/2=209

Answer 18

no i got that problem wrong and it changed: a picture frame is shaped like a rectangle whose perimeter is 418 cm. the length is 10 times as long as the width. find the length and the width

Answer 19

the original post is wrong! as i was typing it i was trying to answer it and i got it wrong!!!!!! so i had to get a similar problem

Answer 20

this is like my 8th problem i am sorry i am stupid and i dont get it!!!

Answer 21

Why didn't you check your post at first !?!

Answer 22

i will remove my post and delete this whole thing i was needing help cause i dont understand not to be looked down upon!!!!

Answer 23

Anyway:
W + 10 W = 418/2
-> 11W = 209
=> W = 19 cm

Answer 24

@nmoore, of course L = 10w = ...?
