Answer 1

Answer:

$13500

Step-by-step explanation:

Given

Each tile cover one ninth of a square yard and each tile costs $3

First, area of the Swimming Pool(from the diagram)

=Area of Left rectangle(length=20,breadth=10)+ Area of Square in middle(side=10)+Area of right rectangle(length=20,breadth=10)

$(\text{area of rectangle}= length\times breadth \\\text{ area of square}= side \times side)$

$= 20\times 10+ 10\times 10+ 20 \times 10\\= 200+100+200\\=500yards$

We have to calculate how many tiles make up 500 yards

As given each tile is one ninth of a yard

⇒Number of tiles that make up 500 yards, n

$=\frac{500}{\frac{1}{9} } =\frac{500\times9}{1} =4500$

⇒ As each tile costs $3

Therefore total cost to tile the floor

$= \text{total number of tiles}\times 3\\=n\times 3\\=4500 \times 3\\=13500$

Therefore total cost of tiles=$13500
