Need help with area and perimeter

there are 2 half circles

and 2 half circles make 1 circle

radius = 20/2 mm = 10mm

so, the

area = area of the rectangle + area of the circle

area = (31*20 + pi*) sq.mm

area = (620 + 314.16) sq.mm

area = 934.16 sq.mm

and perimeter = perimeter of the circle + 2*length of the rectangle

perimeter = 2*10*pi + 2*31 mm

perimeter = 62.832 + 62 mm

perimeter = 124.832 mm

area = 934.16 sq.mm and perimeter = 124.832 mm
