उत्तर
A rectangular piece of dimensions 3 cm × 2 cm was cut from a rectangular sheet of paper of dimensions 6 cm × 5 cm (see the figure). Area of remaining sheet of paper is `bb(underline(24 cm^2))`.
Explanation:
Given dimensions of the bigger rectangle are 6 cm and 5 cm.
∴ Area of bigger rectangle = 6 cm × 5 cm = 30 cm2 ...[∵ Area of rectangle = length × breadth]
Also given, dimensions of the smaller rectangle are 3 cm and 2 cm.
∴ Area of smaller rectangle = 3 cm × 2 cm = 6 cm2
∴ Area of remaining sheet of paper = Area of bigger rectangle – Area of smaller rectangle
= (30 – 6) cm2
= 24 cm2
