Answer to Problem 59STP

  $350$

Explanation of Solution

Given information:

Length of side of each square quilt is 8 inches.

Formula used:

Area of a rectangle is

  $A=\text{length}\times \text{breadth}$

Area of a square is

  $a={\text{side}}^2$

Calculation:

Number of square quilt needed to make a rectangular quilt can be found by dividing the area of rectangular quilt by the area of square quilt.

Number of square quilt can be calculated as

  $\begin{array}{c}n=\frac{160\times 140}{8\times 8}\\ =\frac{20\times 35}{2}\\ =10\times 35\\ =350\end{array}$

Therefore, number of square quilt will be $350$ .
