Question

Determine the number of tiles, to the nearest
integer number, needed to tile a wall.

Dimensions of the tile: 4.5 in. x 4.5 in.

Dimensions of the wall: 7.5 ft. x 11 ft.

Answer 1

Answer:

587 tiles

Explanation:

Step 1: Conversion of feet to inch:-

1 foot = 12 inch

7.5 feet = 7.5 x 12 = 90 inches

11 feet = 11 x 12 = 132 inches

Step 2: Finding area of the wall:-

Area of the wall = length x breadth

= 90 x 132

= 11880 sq. inches

Step 3: Finding area of a single tile:-

Area of the wall = length x breadth

= 4.5 x 4.5

= 20.25 sq. inches

Step 4: Finding required no. of tiles:-

For 11880 sq. inches, we have to multiply the area of a single tile and the total number of tiles(n).

11880 = 20.25 x n

n = 11880 / 20.25

n = 586.67

or, approximately 587 tiles
