If a rectangle has a perimeter of 70, a length of x and a width of x-9, find the value of the length of the rectangle. A) 4, B) 31, C) 13, D) 22

The answer is D) 22

X = 4

Length = 4

Width = - 5

Perimeter = 8 + - 10

Perimeter = - 2

X = 31

Length = 31

Width = 22

Perimeter = 62 + 44

Perimeter = 106

X = 13

Length = 13

Width = 4

Perimeter = 26 + 8

Perimeter = 34

X = 22

Length = 22

Width = 13

Perimeter = 44 + 26

Perimeter = 70
