A reflecting pool is shaped like a rhombus with a side length of 7 meters. What is the perimeter of the pool? Explain how you found your answer.
Select the correct choice below and fill in the answer box to complete your choice.

A. The perimeter of the pool is meters because a rhombus has four equal sides. So, the
perimeter is half the side length.

B. The perimeter of the pool is meters because a rhombus has two equal sides and two sides
half as long. The perimeter is 2 times the side length plus 2 times half the side length.

C. The perimeter of the pool is meters because a rhombus has four equal sides. So, the
perimeter is 4 times the side length.

D. The perimeter of the pool is meters because a rhombus has two equal sides. So, the
perimeter is 2 times the side length.
