Question

Can someone help me with this question please ?

Answer 1

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 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

Answer 2

Explanation:

Area of trapezium = 1/2(a + b)h

a = 7.9cm, b = 10.8cm and h = 6.2cm

Area = 1/2(7.9 + 10.8)×6.2

Area = 1/2 × 18.7 × 6.2

Area = 57.97cm²
