Question

What is its length?

Enter the correct answer,
The perimeter of a rectangle is twice the
sum of its length and its width. The
perimeter is 34 meters and its length is 2
meters more than twice its width.

Answer 1

20

Explanation:

L = 2 x 2w

P = 34

W + W + 2 x 2W + 2 x 2W = P(34)

6W + 4 = 34

-4 -4

6W = 30

divide by 6

W = 5

Plug it back into length equation

L = 2 x 2(5)

L = 2 x 10

L = 20
