Question

Use the three steps to solve the problem. the length of a rectangle is 3 times the width, and the perimeter is 22. find the dimensions of the rectangle. write the solution as decimals.

Answer 1

lengt = 8.25 , width = 2.75

Explanation:

let w be width, then length is 3w

given perimeter is 22 , then

2(3w) + 2w = 22

6w + 2w = 22

8w = 22 ( divide both sides by 8 )

w = 2.75 and 3w = 3 × 2.75 = 8.25

length = 8.25 and width = 2.75
