Question

The width of a rectangle is 7x - 1 feet and the length is 2x + 10 feet. Find the perimeter of the rectangle.

Answer 1

to find the perimeter you do 2lx2w= 2(7x—1= 14x-2
then 2(2x+10)=4x+20
add them together
18x+18 is the awenser

Answer 2

18x +18

Explanation:

We know the opposite sides of a rectangle are always equal, so all you need to do is double both sides and add them together.

(7x-1) + (7x-1) + (2x+10) + (2x+10) = 18x +18
