Answer:4.61 cm
Step-by-step explanation:
area = s(s-a)(s-b)(s-c)
=whole root of 15(15-13)(15-12)(15-5) (s= perimeter/2)
=whole root of 15 * 2 * 3 * 10
=whole root of 3*5*2*3*2*5
=2 * 3 * 5
=30cm^2
again, area= 1/2 * base * height
30 = 1/2 * 13 * height
height = 30 * 2 / 13
= 60/13
= 4.61 cm (approx.)
