In this page perimeter and area solution1 we are going to see solution of some practice questions.
Question 1 :
Sibi wants to cover the floor of a room 5 m long and width 4 m by square tiles.If area of each square tiles is 0.5 m²,then find the number of tiles required to cover the floor of a room
Length of the floor = 5 m
Width of the floor = 4 m
Area of the square shaped tile = 0.5 m²
To find number of tiles required to cover the floor of a room we have to divide the area of floor by area of one tile.
Number of tiles required = Area of floor/Area of one tile
Area of floor:
Floor is in the shape of rectangle,so we have to use area of rectangle formula to find area of the floor.
Area of the floor = Length x Width
= 5 x 4
= 20 m²
Number of tiles = 20/0.5
= 40 tiles
Therefore the required number of tiles = 40
