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

Answer:

The answer is B.

Step-by-step 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 :

$area = \frac{1}{2} \times (a + b) \times h$

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

$area = \frac{1}{2} \times (6 + 16) \times 5$

$area = \frac{1}{2} \times 22 \times 5$

$area = 11 \times 5$

$area = 55 \: {cm}^{2}$
