Problema Solution
The perimeter of a triangle is 51 centimeters.The longest side is twice the length of the shortest side.The third side is three centimeters longer than the shortest side.How long is each side ? Write an equation that represents the problem.
Answer provided by our tutors
We assume the three sides are
X, 2X, (X+3)
So the perimeter = X + 2X + (X+3) = 4X +3 = 51
So the equation is
4X +3 = 51
X=12
