Answer:
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 between the parallel bases and a, b are the bases.
Here h = 6.2, a = 7.9 and b = 10.8, thus
A = 0.5 × 6.2 (7.9 + 10.8)
= 3.1 × 18.7 = 57.97 cm²
