The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?(2 points) Responses 36 inches 36 inches 21 inches 21 inches 30 inches 30 inches 15 inches

Answer 1

The formula for the perimeter of a rectangle is given by:

Perimeter = 2*(length + width)

We are given that the width is 6 inches and the perimeter is 42 inches.

42 = 2*(length + 6)

Dividing both sides of the equation by 2:

21 = length + 6

Subtracting 6 from both sides:

length = 15 inches

Therefore, the length of the rectangle is 15 inches.
