Question

What is the area of the trapezoid?

Answer 1

24 units ²

Explanation:

The area (A) of a trapezoid is calculated as

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

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

Counting the squares in the diagram gives

h = 4, a = 4, b = 8, thus

A =
`(1)/(2)` × 4 × (4 + 8) = 2 × 12 = 24 units²
