Question

How many square tiles of side 50 cm will be needed to fit in a rectangle
floor of a 45m by 25m?​

Answer 1

Area of 1 tile = 50*50 = 2500 cm square

Ar ( floor) = 45*100 *25*100

ar (floor) / ar(tile) = 4500 × 2500 ÷ 2500

= 4500

4500 tiles = answer

Answer 2

4500 tiles is the correct answer.
