Answer:

Explanation:

P=2L+2W

P=34 W= 6.5

34=2L+2*6.5

34=2L+13

2L=21

L=10.5

or

Given:

P = 34 [Perimeter]

W = 6.5 {let's use W and L to make it easy to read]

Also known:

P = W + L + W + L = 2(W+L)

Fill in values:

34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]

. . .

17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]

. . .

10.5 = L [NOTE: This is the solution (the value of L)]

Answer:

10.5

Explanation:

Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5
