Question

Suppose that the width of a rectangle is 5 inches shorter than the length and that the perimeter of the rectangle is 50 inches. The formula for the perimeter of a rectangle is P=2L+2W.
a) Set up an equation for the perimeter involving only L, the length of the rectangle.

Answer 1

What's L in terms of W?

Answer 2

U understand my question?

Answer 3

Let me know...

Answer 4

Aside from L being the legnth and W the width...?

Answer 5

Yes, there is a relationship described in the question, r u able to write it?

Answer 6

I can attach my assignment if you'd like???

Answer 7

"the width of a rectangle is 5 inches shorter than the length"

Answer 8

They mean what does this mean "width of a rectangle is 5 inches shorter than the length". Can you write the width in terms of the length or vice versa? This is the first step to solving this.

Answer 9

Can u write that as a formula?

Answer 10

Think about if I wrote 5 is 5 inches shorter than 10. How would you write that in math?

5 = 10 - 5

Can you use that to now write a general relationship between the length and the width?
