Area of Parallelograms

Question 6 • FL-1205010-M/J Grade 6 Mathematics B -GF

Lorea is designing the top of a quilt which measures 2,160 square inches. Triangles will cover 432 square inches of the quilt, and squares will cover 180 square inches. The rest of the quilt will be parallelograms with a base of 2 inches and a height of 1.5 inches. How many parallelograms should she cut to complete the quilt?

Answer

A

516

B

528

C

617

D

720

Explanation

The parallelograms must cover 2,160 − 432 − 180 = 1,548 square inches. Each parallelogram has area base × height = 2 × 1.5 = 3 square inches. So Lorea needs 1,548 ÷ 3 = 516 parallelograms; the correct choice is 516.
