Question

a,b,c are the sides of a triangoelr and s is its semi perimeter.if s-a =90 cm ,s-b=50cm ,s-c=10cm , then find the value of s​

Answer 1

Answer:

since ...peri=a+b+c

now...first.

s-a=90

a=s-90

similarly..

b=s-50

c=s-10

now using these values...

2×s=a +b+c

2s=s-90+s-50+s-10

2s=3s-150

-s=-150

s=150cm

ans...

Answer 2

Answer:

150

Step-by-step explanation:

s=90+a,s=50+b,s=10+c

3[a+b+c]/2=150+a+b+c

300+2[a+b+c]=3[a+b+c]

300=a+b+c

so,a+b+c/2=150

so,s=150cm
