Answer 1

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.)
