Question

Jack is making a rectangular pattern using square tiles. The length of the rectangular pattern is 24 units, and its width is 6 units. The length of each side of the square tile is 2 units. How many tiles does he need to complete the pattern?

Answer 1

Solution:
● Let’s determine the area of the rectangular pattern.
● The length of the rectangular pattern= 24 units
● The width of the rectangular pattern = 6 units
● Area of a rectangle = Length $\times$ Width
● Area of the rectangular pattern = 24 $\times$ 6


● Area of the rectangular pattern = 144 sq units
● Length of each side of the square tile = 2 units
Now let’s determine the area of the square tile.
● Area of square = Side $\times$ Side
● Area of the tile = 2 $\times$ 2
● Area of the tile = 4 sq units
● Area of the rectangular pattern = Area of tile $\times$ Number of tiles
● So, 144 = 4 $\times$ Number of tiles
● The division equation for this multiplication equation will be,
Number of tiles = 144 $÷$ 4

● Number of tiles = 36

Hence, the correct option is B.
