Answer
We know that,
Area of rectangle = length × breadth
Area of square = side × side.
From figure,
Area of shaded portion = Area of large rectangle - 5 × Area of a small square.
Substituting values we get,
Area of shaded portion = (8 × 6) - (5 × 2 × 2)
= 48 - 20
= 28 cm2.
Hence, area of shaded region = 28 cm2.
