Question

Find the area of the trapezoid by decomposing it into other shapes. A) 48 cm2 B) 55 cm2 C) 66 cm2 D) 96 cm2

Answer 1

The answer is B.

Explanation:

You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :

`area = (1)/(2) * (a + b) * h`

`let \: a = 6,b = 16,h = 5`

`area = (1)/(2) * (6 + 16) * 5`

`area = (1)/(2) * 22 * 5`

`area = 11 * 5`

`area = 55 \: {cm}^(2)`
