Question

Find the area and the perimeter, i just need the Perimeter thanks

Answer 1

`\large\boxed{P=(3\pi+4)\ ft}`

Explanation:

We have 3/4 of a circle and the square.

The perimeter is equal to the sum of a 3/4 of a circumference of a circle and two sides of a square.

The formula of a circumference of a circle:

`C=2\pi r`

r - radius

We have r = 2 ft. Substitute:

`C=2\pi(2)=4\pi\ ft`

3/4 of a circumference:

`(3)/(4)\cdot4\pi=3\pi\ ft`

The length of a side of a square is a = 2ft.

Calculate the perimeter:

`P=3\pi+(2)(2)=(3\pi+4)\ ft`
