Find area. of isosceles triangle whose base is 16cm and it's equal sides is10cm

==========================================

=> here is the solution..................

=> Let's use herons formula to find the area.


Area = √s (s - a) (s - b) (s - c)


Where,

a = 10cm

b = 10cm

c = 16cm


To find s:-


s = a+b+c/2

s = 10 + 10 + 16/2

s = 36/2

s = 18


Area = √s (s - a) (s - b) (s - c)


Area = √18 (18 - 10) (18 - 10) (18 - 16)


Area = √18 × 8 × 8 × 2


Area = √3 × 3 × 2 × 8 × 8 × 2


Area = 3 × 2 × 8


Area = 48cm^2
