Option A:
Area of the shaded part = 99 cm²
Solution:
Length of the rectangle = 15 cm
Width of the rectangle = 9 cm
Area of the rectangle = length × width
= 15 × 9
= 135 cm²
Area of the rectangle = 135 cm²
Side of the square = 6 cm
Area of the square = side × side
= 6 × 6
= 36 cm²
Area of the square = 36 cm²
Area of the shaded part = Area of the rectangle – Area of the square
= 135 cm² – 36 cm²
= 99 cm²
Area of the shaded part = 99 cm²
Option A is the correct answer.
Hence the area of the shaded part of the figure is 99 cm².
