Find the area of the figure shown in the diagram to the nearest hundredth.
a) 16.00 m2
b) 28.57 m2
c) 41.13 m2
d) 49.12 m2

Choice C) 41.13 square meters



This figure is a composition of two quarter-circles and a square

Area of quarter circle = (1/4)*(area of circle)
Area of quarter circle = (1/4)*(pi*r^2)
Area of quarter circle = (1/4)*(pi*4^2)
Area of quarter circle = (1/4)*(pi*16)
Area of quarter circle = (1/4)*16*pi
Area of quarter circle = 4pi
There are two quarter circles, so the two circular areas add to 4pi+4pi = 8pi

Area of square = s*s = 4*4 = 16 square meters

Add the square area to the circular area: 8pi+16

Now use a calculator to find 8pi+16 = 41.1327412287183 which rounds to 41.13

21/2 or 5/2
