Question

a, b, c, are the sides ofa triangle and s is its semi-perimeter. If (s-a)=90 cm, (s-b)=50 cm, and (s-e)=10 cm, then find the value ofs.​

Answer 1

Answer:

150

Step-by-step explanation:

2s=a+b+c

s-a=90

+ s-b=50

2s-(a+b)= 140

so c =140

similarly

a=60

b=100

hence s = 60+100+140 = 150
