What is the area of this trapezoid?

Sonja [21]

Answer:

$\boxed{Area \: of \: trapezoid = 126 \: {in}^{2}}$

Given:

AB = 12 in.

DF = 2 in.

FE = 12 in.

EC = 2 in.

BE = 9 in.

Step-by-step explanation:

$Area \: of \: trapezoid = \frac{1}{2} (sum \: of \: parallel \: sides) \times height$

Parallel sides are:

AB = 12 in

DC = DF + FE + EC

= 2 + 12 + 2

= 16 in.

Height:

BE = 9 in.

$Area \: of \: trapezoid = \frac{1}{2}(12 + 16) \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{2 } \times 28 \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 14 \times 9 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 126 \: {in}^{2}$
