Find the Area of the figure below, composed of a rectangle with a semicircle removed from it. Round to the nearest tenths place.

Area of the figure = 25.7 units²

Step-by-step explanation:

Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD

Area of the rectangle ABCD = Length × Width

                                               = BC × AB

                                               = 8 × 4

                                                = 32 units²

Area of the semicircle =

Here, r = radius of the semicircle

r =

r =

r =

r = 2 units

Therefore, area of the semicircle =

                                                       = 2π

                                                       = 6.28 units²

Area of the given figure = 32 - 6.28

                                         = 25.72 units²

                                         ≈ 25.7 units²

the perimeter is increased by a factor of 2

answer: 1 + 1 = 11
