Two semicircles are placed in a rectangle. The width of the rectangle is 7 cm.

Find the area of the shaded region. Use the value 3.14 for pi , and do not round your answer.

Step-by-step explanation:

length=4×7=28 cm

width=7 cm

area of rectangle=28×7=196 cm²

area of two equal semicircles =area of circle=π×7²=49π

area of shaded region=196-49π=49(4-π)≈49(4-3.14)≈49×0.86≈42.14 cm²
