Question

The expression to find the perimeter of a rectangle is 2(length + width). What is the 1 perimeter, in units, of a rectangle of length 7 unit and width 2 unit? ​

Answer 1

18/14 but reduced it would be 9/7

Explanation:

Formula :P = 2(L + W)

You would change them into fractions over one, which os the 1 perimeter.

L = 1/7

W = 1/2

P = 2(L + W)

P = 2(1/7 + 1/2)

P = 2(2/14 + 7/14)

P = 2(9/14)

P = 18/14 which reduces to 9/7

Answer 2

The answer would be 18 units I believe

2(7+2)
2(9)
18 units
