The width of a rectangle is 6t-6.5 feet and the length is 6.5t+10 feet. find the perimeter

The perimeter is equal to 25t + 7.

W = 6t - 6.5

L = 6.5t + 10

P = 2l + 2w

Plug the values for l and w into the third equation to solve for perimeter.

P = 2 (6.5t + 10) + 2 (6t - 6.5)

Distributive property.

P = 13t + 20 + 12t - 13

Combine like terms.

P = 25t + 7
