Question

Part 1:

The length of a rectangle is 4/3 its width, w.

Which expression represents the perimeter of the rectangle?

Answer Choices:

a. 4/3w+2w


b. 4(4/3w+w)


c. 4×4/3w


d. 2(4/3w+w)


Part 2:

The perimeter of the rectangle from Part 1 is 28 inches.

What is the area of the rectangle, in square inches?

Answer 1

perimeter = 2 times the length plus 2 times the width

which can also be written as 2(4/3w+w) so the answer is D

part 2

28 = 2(4/3w+w) when you do the calculation w = 6

length = 4/3 *6 = 8

area = 6 * 8 =48 square inches
