Question

An isosceles triangle has a abuse 6 cm long and one of the equal side is 5 cm long. Find the area of the triangle​

Answer 1

hlo mate ✌️

semi-perimeter (s)= (a +b + c)/2

here ∆ is an isosceles

So , semi - perimeter (s) = (2a + c)/2

Now,

Area = √s(s-a)(s-b)(s-c)

Here ,

S = (10 + 6)/2 = 8

a = 5cm ; c = 6cm

Putting the value -:

Area = √8(8-5)(8-5)(8-6)

Area = √8×3×3×2

Area = √144

Area = 12 cm×cm

Hope it helps ❣️
