Question

Calculate the area of this trapezium.
7.9 cm
6.2 cm
10.8 cm

Answer 1

A = 57.97 cm²

Explanation:

The area (A) of a trapezium is calculated as

A =
`(1)/(2)` h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 6.2, a = 10.8 and b = 7.9, thus

A =
`(1)/(2)` × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
