Question

Find the area of this figure ​

Answer 1

29.58 mi²

Explanation:

Area = 1/2 (5.4 + 12) × 3.4

Area = 1/2 × 17.4 × 3.4

Area = 29.58 mi²

Answer 2

29.58 mi²

Explanation:

The figure is a trapezium and area can be calculated using the formula

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

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

here h = 3.4, a = 5.4 and b = 12

A = 0.5 × 3.4(5.4 + 12) = 1.7 × 17.4 = 29.58 mi²
