Question

Find the cost of tiling a rectangular floor 10 m by 14 m if square tiles with side 1 m are used. The price of a tile is $5.20.

Answer 1

Answer:

Cost of tiling house = $728

Step-by-step explanation:

Given dimensions of rectangular floor: 10m x 14m

Area of floor = Length x Breadth = 14 x 10 = 140m²

Given, side of each tile = 1m

Area of each tile = side² = 1² = 1m²

Let the total number of tiles used for tiling the floor be n

We know that total area covered by tiles = Area of floor

n x Area of 1 tile = Area of floor

n x 1 = 140

n = 140

So, 140 tiles were used

Given, cost of 1 tile = $5.20

∴ Cost of 140 tiles = 140 x $5.20 = $728
