Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 42-m-42-m square. Val says the area is 1,005.48m squared. Find the area enclosed by the figure. Use 3.14 for our. What error might Val have made?

The area enclosed by the figure is 4533.48 square meters.

Step-by-step explanation:

Side length of the square = 42m

The semicircle is attached to each side of the square. So the diameter of the semicircle is the length of the square.

Radius of the semicircle = 21m

Area of the square = 42 x 42 = 1764 square meters

Area of 1 semicircle = π(21 x 21) /2

= (3.14) (441) /2

= 1384.74/2

= 692.37 square meters

Area of 4 semicircle = 4 x 692.37

= 2769.48 square meters

Total area = 1764 + 2769.48

= 4533.48 square meters

The area enclosed by the figure is 4533.48 square meters.
