Answer:

A = 57.97 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] 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 = [tex]\frac{1}{2}[/tex] × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
