Question

Q. Find the perimeter and area of the following figure-​

Answer 1

area = side ^2 = 10^2 = 100 cm^2

perimeter = perimeter of square + perimeter of half circle

perimeter of square = 4a = 4×10 = 40 cm

diameter of circle = 10 cm

radius = 10/2 = 5 cm

perimeter of half circle = 2* pi* r /2 = pi*r = 3.14 × 5 = 15.70 cm

so total perimeter = 40 + 15.70 = 55.70 cm
