Question

What is the area of the back yard? A. 1184 ft2B.90 ft 2C.928 ft 2D.24864 ft2

Answer 1

Given a backyard in a trapezoidal shape;

Where;

`a=21ft,b=32ft,c=37ft`

The area, A, of the trapezoid is;

`A=(1)/(2)(a+c)b`

Thus;

`\begin{gathered} A=(1)/(2)(21+37)32 \\ \\ A=(58)16 \\ \\ A=928ft^2 \end{gathered}`

CORRECT OPTION: C
