Question

If sides of triangle are 5 cm ,12cm,and 13 cm,then the area of triangle will be?

Answer 1

let,

Side a=5

Side b=12

Side c=13

Using Heron's Formula,

S= a+b+c/2

=5+12+13/2

=15

Area= $\sqrt{s(s-a)(s-b)(s-c)}$

$\sqrt{15(15-5)(15-12)(15-13)}$

=3*5*2

=30 cm^2

Answer 2

Answer:

= 30 × 5 × 2

= 300 cm²
