A circular ground whose diameter is 30 meters, has a 1.5 m broad garden around it. What is the area of the garden in square meters.

$148.5 m^2$

A circular ground whose diameter = 30 meters

Park width = 1.5m

We can say total diameter of the area = 30 + 1.5 + 1.5 = 33

So, area of the circle = πr²

so the area of the park = π(R² - r² )

= \(\frac{22}{7}\) × (16.5² - 15² )

= 148.5 cm²
