Question

The length of three sides of a triangle are 20cm, 16cm and 12cm. find the area of the triangle solve

Answer 1

chk out the solution .. plz

Answer 2

Answer:

Step-by-step explanation:

The given sides are a=20 b=16 c=12

so first find out the perimeter so,

p=a+b+c

p=20+16+12=48cm

So, now find out side

2s =48

s=24cm so, now let's find out area

Area=√(s-a) (s-b) (s-c)

A=√24(24-20)(24-16)(24-12)

=√24(4)(8)(12)

=√2*2*3*2*2*2*2*2*2*2*2*3

=2*2*2*2*2*3=48cm

Hence area of the triangle is 48cm
