Question

What is the perimeter and area of this figure? Round to the nearest whole number.

Answer 1

Answer:

Perimeter = 27.85

Area = 94.7units^2

Step-by-step explanation:

the figure is made up of 3 squares and 1/4 of a circle, we find the area by adding the areas of the squares and the area of ​​1/4 of a circle.

Area of ​​the squares

5 x 5 x3 = 75units ^ 2

we find the area of ​​1/4 of a circle

Area = π × r2

3.14 x 5 ^ 2 =

78.5

let's divide by four

78.5: 4 =

19.7units ^ 2

let's add up the areas

75 + 19.7 =

94.7units ^ 2

we find the perimeter

10 + 10 + 5 + 5 =

20units

we add the perimeter of 1/4 of a circle

2πr: 4

2 * 3.14 * 5: 4 =

7.85units

we add up

20 + 7.85 =

27.85units

Answer 2

Answer:

Step-by-step explanation:

This figure is quarter of a circle.

=> Perimeter = π/2r + 2r

=> 5π + 10

=> 5(3.14) + 10

=> 15.7 + 10

=> 26 units

Area = πr²/4

=> 3.14 x 100 / 4

=> 25 x 3.14

=> 79 sq. units
