Question

What is the area of a trapezoid that has bases measuring 19 centimeters and 23 centimeters, and a height of 14 centimeters?

Answer 1

Area of a trapezoid, A = 1/2 × (a + b) h, where a = 19 cm, b = 23 cm & h = 14 cm.

By substitution, we have

A = 1/2 × (19 + 23)14

= 1/2 × 14(19 + 23)

= 1/2 × 14(42)

= 7(42)

= 294 sq. cm
