What is the total area, in square inches, of the shaded sections of the trapezoid below?

Otrada [13]

Answer:

64.5 in²

Explanation:

$\sf area \ of \ trapezoid = \dfrac{1}{2} * ( a + b) *h$

Solve for the entire trapezoid:

$\hookrightarrow \sf \dfrac{1}{2} * ( 6.5 +(9.8+5.2+6.5) ) *8.6$

$\hookrightarrow \sf 120.4 \ in^2$

Solve for the unshaded rectangle:

Length * Width

6.5 * 8.6

55.9 in²

Area of the shaded region:

120.4 in² - 55.9 in²

64.5 in²
