Question

the perimeter of a triangle is 30 cm. The length of first side is 1 cm longer than the second side. The third side is 1 cm more than twice the second side. What is the length of the first side

Answer 1

Answer:

8

Step-by-step explanation:

perimeter a + b + c = 30

according to the given question,

a = 1+b

c= 1+ 2b

so, a +b+c= 1+ b+b+1+2b=30

4b+2= 30

4b = 30-2=28

b= 28/4=7

therefore, a= 1+b

a= 1+7= 8
