Question

A kitchen of the given form needs to be tiled. If the tiles needed per sq ft is 4, then the number of tiles needed for the total area is

• A. 450
• B. 700
• C. 500

Answer 1

The correct option is B 700

The given figure is


It consists of two rectangle and one square.

Area of Rectangle1 = base $\times$ width

Base of the Rectangle1 = 10 ft

Width of the Rectangle1 = 15ft

Area = 10 $\times$ 15 = 150 sq ft



Area of Rectangle2 = base $\times$width

Base of Rectangle2 = 10 ft

Width of Rectangle2 = 5 ft

Area of rectangle2 = 10$\times$5= 50 sq ft



Area of square = side $\times$ side

Area = 5 $\times$ 5 = 25 sq ft



Hence, total area = 150 + 50 + 25 = 175 sq ft

Tiles needed per sq ft = 4

Tiles needed for 175 sq ft = 175 $\times$ 4 = 700

Hence, the number of tiles needed = 700
