Find the area of an equilateral triangle whose area is equal to the triangle of sides 12 cm, 8 cm and 16 cm.
We can get the area of another triangle by using Heron’s formula
a = 12 cm, b = 8 cm and c = 16 cm
s =a+b+c2 = 18 cm
Area = √s(s−a)(s−b)(s−c)
Find the area of an isosceles triangle, whose unequal side is 12 cm and the perimeter of triangle, is 60 cm.
The area of a triangle whose sides are 13cm, 12cm & 5cm is
