Question

Asim is going to cover the path with paving.Each paving stone is a square of side 30 cm.Each paving stone costs £2.50

Answer 1

We have been given Asim is going to cover the path with paving. Each paving stone is a square of side 30 cm.

Let us find area covered by each stone.

Since the paving stone is square, so it area would be square of each side length.

$\text{Area of paving stone}=(\text{30 cm})^2=900\text{ cm}^2$

The dimension of rectangular path are 630 cm and 120 cm.

We know that area of rectangle is width times length, so area of garden would be length times width.

$\text{Area of rectangular path}=75600\text{ cm}^2$

To find the number of stones, we will divide area of path by area of each stone.

$\text{Stone used to cover the path}=\frac{75600\text{ cm}^2}{900\text{ cm}^2}$

$\text{Stone used to cover the path}=84$

Therefore, it will take 84 stones to cover the path.

We have been given that each paving stone costs £2.50, so total cost would be $2.50\times 84=210$.

Therefore, it will cost £210.
