The sum of all sides of triangle is 48 m and in radius is 7.5 m then find the area of triangle?
1. 180 square m
2. 210 square m
3. 220 square m
4. 240 square m
1. 180 square m
2. 210 square m
3. 220 square m
4. 240 square m
Correct Answer – Option 1 : 180 square m
Given:
The sum of all sides of the triangle is 48 m and in radius is 7.5 m
Formula used:
Area of the triangle = (sum of all sides × r)/2
Where r is the radius of the incircle
Calculation:
By using the given formula
∴ Area = (48 × 7.5)/2 = 180 square m
Hence, option (1) is correct
