Answer: area = 7.14 inches²
Perimeter = 10.28 inches
Step-by-step explanation:
The diagram contains a square and two semicircles.
The formula for determining the area of a semicircle is expressed as
Area = 1/2πr²
Radius = diameter/2 = 2/2
Radius = 1 inch
Area of semicircle = 1/2 × 3.14 × 1²
Area = 1.57 inches²
Area of second semicircle = 1.57 inches²
Area of the square is
2² = 4 inches²
Area of the given figure is
1.57 + 1.57 + 4 = 7.14 inches²
The formula for determining the perimeter of the semicircle is expressed as
Perimeter = 1/2 × πd
Perimeter = 1/2 × 3.14 × 2 = 3.14 inches
Perimeter of the given figure is
3.14 + 3.14 + 2 + 2
= 10.28 inches
