Question

Find the area of the rhombus.

A parallelogram with base length 22.5 millimeters, and height 20 millimeters. All side lengths are the same.
b. The area of the parallelogram is

65 ft2. What is its height?

A parallelogram with base length 213 feet, and height h.

Answer 1

Area of a parallelogram (and a rhombus) = base × height.

a) base = 22.5 mm, height = 20 mm
Area = 22.5 × 20 = 450 mm².

b) Given area = 65 ft² and base = 213 ft, solve 65 = 213·h:
h = 65/213 ft ≈ 0.305 ft ≈ 0.305·12 = 3.66 inches (about 3.66 in).
