Perimeter and Area Solution1





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

Solution:

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

Number of tiles = 20/0.5

                      = 40 tiles

Therefore the required number of tiles = 40
