Answer:
72.56 square cm
Stepbystep explanation:
Area of rectangle = 15 · 4
Area of rectangle = 60
semicircles at each end of rectangle equals one full circle
Area of circle = π · r²
Area of circle = π · 2²
Area of circle = 4π
Area of circle = 4(3.14) = 12.56
Add area of rectangle to area of circle:
60 + 12.56 = 72.56
