Question

the sides of a triangle are 16cm,12cm and 20cm.find its area?​

Answer 1

Step-by-step explanation:

Area of triangle = Add 3 sides

16+12+20 = 48cm

Answer 2

Answer:

a=16

b=12

c=20

semi perimeter=a+b+c/2

16+12+20/2

=24cm

USING HERON'S FORMULA

area of triangle=under root s (s-a)(s-b)(s-c)

= under root 24× (24-16)(24-12) (24-20)

= under root 24 ×8×12×4

= under root 12×2×2×4×12×4

=12×2×4

=96 cm^2
