Answer 2

Hi,

Here is your answer.

Given Data,

Ten triangular pieces of cloth each measuring 60cm , 60cm , 20cm

We know that,

           S = Perimeter/2

Here we need to Heron's Formula:-

            →   √s(s-a) (s-b) (s-c)

            → 60 + 60 + 20/2 

            → 140/2 = 70

Now,  √70 × (10)² × 50 

    = √35 × 10 × 10 × 10 × 10

Area of 10 pieces = 100√35

  = 1000√35  AREA OF REQUIRED CLOTH
