Class : IX
almond37 [142]

Step-by-step explanation:

a=8cm

b=15cm

c=17cm

s=a+b+c/2

 =8+15+17/2

 =40/2

 =20

Using heron's formula,

ar. of triangle= √s(s-a)(s-b)(s-c)

                     =√20(20-8)(20-15)(20-17)

                     =√20×12×5×3

                      =√2×2×5×2×2×3×5×3

                      =2×2×3×5

                      =60cm²

On side 17cm,

Ar. of triangle=1/2×b×h

60=1/2×17×h

∴h=60×2/17

    =7.05 cm
