Answer 1

Given:

A portion inside a rectangle of length 5 m and breadth 2 m is shaded in the form of a square of side 2 m

Calculation:

⇒ area of rectangle = 5 × 2 = 10 m²

⇒ area of shaded square = 2 × 2 = 4 m²

⇒ area of unshaded portion = (10 - 4) = 6 m²

∴ required ratio of the area = 4/6 = 2 : 3
