$\tt\pink{⎝⎝\:For \:Example:}$ Find the area of triangle having three sides as 4 cm, 6 cm and 8 cm using Heron's formula. Let a = 4 cm, b = 6 cm and c = 8 cm. Therefore, s = $\frac{(a + b + c)}{2}$ = $\frac{(4 + 6 + 8)}{2}$ = 9 cm. For Example: An isosceles triangle has perimeter 30 cm and each of the equal sides is 12 cm.❤
