Question

The perimeter of a parallelogram is 72 inches, and

1 side measures 12 inches. What are the lengths, in
inches, of the other 3 sides?
A. 12, 12, 36
B. 12, 18, 18
C. 12, 24, 24
D. 12, 30, 30
E. Cannot be determined from the given information

Answer 1

C

Explanation:

It stats that there are 4 sides, so you can assume the parallelogram is a rectangle. Rectangles have congruent sides, once you know one side you know the opposite. At this given side, you would already know 2 of the sides are 12 inches. 72-12=48. The last 2 sides are congruent, so you take 48/2=24.

Answer 2

The answer is C Since its a parallelogram, the opposite side is also 12. 12+12=24, 72-24=48, 48/2=24 which is the other 2 sides
