Question

There is a circular lawn of radius 28 metre. A path of seven metre width is laid around the lawn. What will be the area of the path? Solve the problem

Answer 1

The area of the path is 198 sq. cm.

Step-by-step explanation:

Since we have given that

Radius of circular lawn r = 28 m

Width of path = 7 m

So, Outer radius R = 28+7 =35 m

So, Area of path would be

$\pi (R^2-r^2)\\\\=\dfrac{22}{7}\times (35^2-28^2)\\\\=\dfrac{22}{7}\times 7\times 63\\\\=22\times 9\\\\=198\ cm^2$

Hence, the area of the path is 198 sq. cm.
