Step-by-step explanation:

According to pythogaras theorem,

5² + 12² = 13²

=> 5 & 12 or 12 & 5 is the base and altitude of the triangle respectively.

=> Area = ½ x base x altitude

= ½ x 5 x 12 = 30 cm²

Use Heron’s Formula

A = √{s(s - a)(s - b)(s - c)} where s = (a+b+c)/2

=> s = (5+12+13)/2 = 15

Area = √(15x 10 x 3 x 2) = √900 = 30 cm²
