A triangle with equal sides has perimeter 9 cm. Then find the area of the triangle

Text Solution

Verified by Experts

The correct Answer is:
`2 sqrt2 cm^(2)`
The only possible set of sides can be 3, 3, 2 (as sum of any two side must be greater than the third one)
So, `Delta = sqrt(s(s -a) (s-b) (s-c))`
`= sqrt(4 xx 1 xx 1 xx 2) = 2sqrt2 cm^(2)`
