Question

The perimeter of a triangle is 65 centimeters. The second side is twice the first and the third side is 3 and 1/2 times the first side. Find the length of each side. (Hint: P = a + b + c)

Answer 1

X=first number
2x= second side
3.5x= third side


X+2x+3.5x=65

6.5 x= 65
Divide both sides by 6.5

X=10. First side
2x= 20. Second side

3.5x= 35 = third side

10, 20, 35
