Question

An isosceles triangle with equal side 10 cm each and third side 8 cm ​

Answer 1

Answer:

Then your question is find thee area na ?

Sol;

By herons formula √s(s-a)(s-b)(s-c)

S= a+b+c/2 = 10+10+8/2 = 28/2 = 14

So

√14(14-10)(14-10)(14-8) = √14×4×4×6

√7×2×4×4×3×2 = 8√21Cm²

So the area of isoscles triangle is = 8√21cm²Ans
