Question

A floor is 5 m 40 cm long and 3 m 75 cm wide. Find the area of the carpet required to cover the floor?

• A. 20.25 sq. m
• B. 20.52 sq. m
• C. 20.15 sq. m
• D. 20.51 sq. m

Answer 1

The correct option is A

20.25 sq. m

Length of the floor, l = 5 m 40 cm = 5.4 m
[$\because$ 100 cm = 1 m]

Breadth of the floor, b = 3 m 75 cm = 3.75 m

Area of the floor, $A=l\times b$
$\Rightarrow A=5.4\times 3.75$
$\Rightarrow A=20.25m^2$

Area of the carpet required to cover the floor = Area of the floor
= 20.25 m${}^2$
