Answer 2

Answer:

Given: Sides of triangle = 25,39& 56

To find: area of triangle

Solution:

Let a = 25

b = 39

c = 56

∴ Semi - perimeter (s) = a+b+c/2

= 25+39+56/2

= 120/2

s = 60

Now, by using Heron's Formula,

=√s(s - a)(s - b)(s - c)

= √60(60-25) (60-39) (60-56)

= √ 60 × 35 ×21 ×4

= √ 3 ×2 ×2 ×5 ×7 ×5 ×3 ×7 ×2 ×2

= 2 ×2 ×7 ×5 ×3

= 420 ans...
