Step-by-step explanation:
To find the shaded area, subtract the area of the semicircle from the area of the rectangle.
<u>Formulae</u>
<u>Area of rectangle</u>
Given dimensions of the rectangle:
- width = 7 cm
- length = 11 cm
Substituting these values into the formula:
<u>Area of semicircle</u>
Diameter of semicircle = 11 - 2 - 2 = 7 cm
⇒ Radius (r) = 7 ÷ 2 = 3.5 cm
<u>Area of shaded region</u>
= area of rectangle - area of semicircle
= 77 - 19.25
= 57.75
