Q2 of 131 Page 226

A rectangular piece of dimensions 3 cm × 2 cm was cut from a rectangular sheet of paper of dimensions 6 cm × 5 cm (Fig. 9.14).

Area of remaining sheet of paper is


Dimensions of bigger rectangle are 6 cm × 5 cm


So area of bigger rectangle


= 6 cm × 5 cm


= 30cm2


Now,


Dimension of smaller rectangle = 3 cm × 2 cm


Area of smaller rectangle = 3 cm × 2 cm


= 6 cm2


Area of remaining sheet = area of bigger rectangle - Area of smaller rectangle


⇒ 30 – 6


⇒ 24 cm2
