Calculate the area of the shaded region in each figure. Use 3.14 and round to the nearest tenth, if necessary.

Given:

Given that the length of the side of the square is 12 cm.

The  given figure consists of two circles with radius of 3 cm each.

We need to determine the area of the shaded region.

Area of the square:

The area of the square can be determined using the formula,

Substituting s = 12, we get;

Thus, the area of the square is 144 square cm.

Area of the two circles:

The area of the circle can be determined using the formula,

Substituting r = 3, we get;

The area of 2 circles is given by

Thus, the area of the two circles is 56.52 square cm.

Area of the shaded region:

The area of the shaded region can be determined by subtracting the area of the two circles from the area of the square.

Thus, we have;

Area = Area of square - Area of two circles.

Substituting the values, we get;

Thus, the area of the shaded region is 87.5 square cm.
