Question

A rectangular tile measures $10cm\times 20cm$. Find the area of a floor covered by 10 such tiles.

• A. 20000 $c{m}^2$
• B. 2000 $c{m}^2$
• C. 4000 $c{m}^2$
• D. 40000 $c{m}^2$

Answer 1

The correct option is B 2000 $c{m}^2$

The area of a rectangle is the product of length and width.

Area of 1 tile, $A=10cm\times 20cm=200c{m}^2$
The area covered by 10 such rectangular tiles,
$10A=10\times 200c{m}^2=2000c{m}^2$
