What is the area of this figure?

Use 3.14 for pi.

Enter your answer in the box. Round only your final answer to the nearest whole number.

Answer 1

the answer is 157ft²

Explanation:

i hope this helps;)

Answer 2

`157\ in^(2)`

Explanation:

we know that

The area of the figure is equal to the area of rectangle plus the area of two semicircles

The area of rectangle is equal to

`A=14*5=70\ in^(2)`

The area of the small semicircle is equal to

`A=\pi r^(2) /2`

`r=5/2=2.5\ in` -----> radius is half the diameter

substitute

`A=(3.14)(2.5^(2))/2=9.8125 in^(2)`

The area of the larger semicircle is equal to

`A=\pi r^(2) /2`

`r=14/2=7\ in` -----> radius is half the diameter

substitute

`A=(3.14)(7^(2))/2=76.93\ in^(2)`

The area of the figure is equal to

`70+9.8125+76.93=156.7425=157\ in^(2)`
