Answer:
Area = 12 + 6.25π ft², Perimeter = 6 + 5π ft
Step-by-step explanation:
Area:
So I would break this shape into a triangle and a circle (the two semi-circles make a full circle).
Formula for Area of a Triangle: base · height ÷ 2
6 · 4 ÷ 2 = 24 ÷ 2 = 12
Formula for area of a circle: π · radius²
π · (5/2)² = 6.25π
Area of entire shape: Triangle + Circle
Area = 12 + 6.25π ft²
Perimeter:
So the perimeter is made up of the base of the triangle plus the circumference of the circle.
Base of Triangle: 6
Formula for circumference: 2rπ
5 · π = 5π
Perimeter = 12 + 5π ft
