Chapter 1.6, Problem 48HP

To determine

To find number of tiles

Answer to Problem 48HP

Number of tiles that can fit is 10.

Explanation of Solution

Given information:

  $length=20,breadth=12.5$

  $side=5$ inches

Formula used:

  Area of rectangle= $length\times breadth$

  Area of square= ${(side)}^2$

Calculation:

According to question,

  No of tiles= $\frac{area(rect)}{area(square)}$

Substituting formula,

  No of tiles= $\frac{length(breadth)}{sid{e}^2}$

Substituting values,

  No of tiles= $\frac{20\times 12.5}{5^2}$

Solving,

  = $\frac{20\times 12.5}{5\times 5}$

So,

  = $\frac{4\times 12.5}{5}$

Hence, number of tiles that can fit is 10.
