Answer 2

Help please

Answer 3

@dan815

Answer 4

Ill give medal and ill fan those who help.

Answer 5

I'll help you. :)

Answer 6

Here's how I see, it: there are two triangles there.

Answer 7

That means you can use 1/2bh = a

Answer 8

So use that to find the lengths of each side.

Answer 9

I am finding the a and b sir... I have the area of the rectangle but i am finding the perimeter of it.

Answer 10

and the diagonal is 194

Answer 11

OHHH lol

Answer 12

The Diagonal is the square root of (width squared + height squared):
d = sqrt(w^2 + h^2)

Answer 13

so i have to find the a and b in order to compute the perimeter.

Answer 14

Yes, but you'll have two equations that a and b will have to fit.
d = sqrt(a^2 + b^2)
and
2(a + b)

Answer 15

Are you given any answer choices?

Answer 16

nope i have to find it. our instructor just reverse the question he gave us . Its finding the area.

Answer 17

so a = b * h

Answer 18

you're given d, which is sqrt(a^2 + b^2)

Answer 19

and you need to solve for p, which is 2(a + b)

Answer 20

Gah, I can't see the connection. Do you?

Answer 21

I think there is something wrong with the problem

Answer 22

So do I.

Answer 23

There isn't a calculator online that I can find that can use the variables given and find a and b.

Answer 24

I think We have to derive a new formula but . I think there's no formula that we can derive because it is perimeter and the formula for the perimeter of a rectangle is PERIMETER = 2L+2W and the are is A=LXW

Answer 25

Area of rectangle,A= a*b = 18720
perimeter, P = 2a + 2b
a^2 + b^2 = 194^2
from the area we can substitute for a or b
use this expression in the eqn with D to find b
now that you have a and b calculate P

Answer 26

No our teacher just reverse the question there
is nothing wrong with the area

Answer 27

What? Can you elaborate it please

Answer 28

sorry I did not have D^2 which would be 194^2

Answer 29

are you asking to go through the steps above?

Answer 30

the perimeter is 548 but how can i get the a and b . I use the pythagorean theorem then i dont know what is next

Answer 31

Steps please

Answer 32

give me a minute i think i found a "short-cut"

Answer 33

is the question still to find the perimeter or is the question changed and the perimeter is now 548 given

Answer 34

are you there? I want to answer the right question?

Answer 35

@triciaal hey the perimeter is 548

Answer 36

Help please anyone

Answer 37

anyone help please

Answer 38

@imer

Answer 39

Given : Area = 18720 D= 194 b= ?
since its regtangle
then rectangle area=a*b
Hence :-

ab=18720
and
a^2+b^2=194^2
