# 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

a. 30 cm²

b. 36 cm²

c. 24 cm²

d. 22 cm²

**Solution:**

It is given that

Length of rectangle = 6 cm

Breadth of rectangle = 5 cm

We know that

__Area__ of bigger rectangle = length × breadth

Substituting the values

= 6 × 5

= 30 cm²

Similarly

Dimensions of smaller rectangle are 3 cm and 2 cm

Area of smaller rectangle = 3 × 2

= 6 cm²

Here

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

Substituting the values

= 30 - 6

= 24 cm²

Therefore, the area of the remaining sheet of paper is 24 cm².
