Question

Please help. The perimeter of a rectangle is equal to twice the sum of its length and it width. One rectangle has a length of 13 1/8 inches and a perimeter of 42 1/2 inches. Write an equation that can be used to find the width,w, if the rectangle.

Answer 1

Do you know how to setup a model for this problem?

Answer 2

No I don't.

Answer 3

You would divide it by 2, then subtract the height

Answer 4

the perimeter

Answer 5

Divide what by 2?

Answer 6

To start, draw the rectangle with labels for length (L) and height (H).

Answer 7

Ok..

Answer 8

@BrandonH4499 is right. The model of the problem is P = 2L + 2H.

Answer 9

Do you see how to get H? (I call it H, height, but your problem uses W for width). In that case P = 2L + 2W

Answer 10

No I mean 8
