Question

A rectangular tile measures 5 cm $\times$ 3 cm. is the area of a floor covered by 10 such tiles.

• A. 150 $c{m}^2$
• B. 300 $c{m}^2$
• C. 200$c{m}^2$

Answer 1

The correct option is A 150 $c{m}^2$

$\text{The area of a rectangle}=\text{length}\times \text{width}=5\times 3=15{\text{cm}}^2$
Hence, the area covered by 10 such rectangular tiles = 10 $\times$ 15 $c{m}^2$
= 150 ${\text{cm}}^2$
