Question

To cover the squared floor of a room there are 400 tiles required if each side 0.2m find the side of squared floor

Answer 1

Answer:

4m

Step-by-step explanation:

Area of 1 tile = 0.2*0.2 = 0.04m²

Area of 400 tiles = 0.04*400 = 16m²

This area is the area of the square room.

Now side of square room = √16m² = 4m
