Question

Find the area of the trapezoid l. If the answer is not an integer, leave it in simplest radical form. The figure is not to scale.

A= Ft

Answer 1

42 ft²

Explanation:

Area of trapezoid = ½(a + b)h

a = 9 ft

b = 3 + 9 = 12 ft

h = √(5² - 3²) = 4 ft (pythagorean theorem)

Plug in the values

Area = ½(9 + 12)*4

Area = ½(21)*4 = 42 ft²
