## Answers ( No )

The length is equal to 25.The width is equal to 15.l = 2w – 5

2l + 2w = 80

We have a value for l, so we can plug it into the second equation to solve for w.

2(2w – 5) + 2w = 80

Distributive property.

4w – 10 + 2w = 80

Combine like terms.

6w – 10 = 80

Add 10 to both sides.

6w = 90

Divide both sides by 6.

w = 15

Now that we have a value for w, we can plug it into the original equation to solve for l.

l = 2(15) – 5

l = 30 – 5

l = 25
