Question

Find the area of the figure to the nearest thousandth. Use 3.14 for π.

Answer 1

The area of the figure is
`236.625\ ft^(2)`

Explanation:

we know that

The area of the figure is equal to the area of semicircle plus the area of rectangle plus the area of semicircle

so

The area of the figure is equal to the area of a circle plus the area of rectangle

`A=\pi r^(2)+bD`

we have

`r=15/2=7.5\ ft` ----> the radius is half the diameter

`D=15\ ft`

`b=4\ ft`

substitute the values

`A=(3.14)(7.5^(2))+4*(15)=236.625\ ft^(2)`
