Question

the sides of a triangle are 16 cm ,30cm, 34cm . it's area is
a) 225 b)225√3 c)225√2 d)450
pls show the answer with the calculations

Answer 1

ans

the side of triangle = 16 cm 30cm 34cm

s=p/2. = 16+30+34/2 =40

s=40

area of triangle = √s (s-a) (s-b) (s-c)

s - a = 40 - 16 = 24

s - b = 40 - 30 = 10

s - c = 40 - 34 = 6

√40×24×10×6

ans = 240
