Problema Solution
The perimeter of a triangle is 33 centimeters. The first side is 5 centimeters shorter than the second, and the third is twice the first. Find theb lengths of the sides
Answer provided by our tutors
let
a = the length of the first side
b = the length of the second side
c = the length of the third side
perimeter of a triangle is 33 centimeters
a + b + c = 33
the first side is 5 centimeters shorter than the second
a = b - 5
the third is twice the first
c = 2a
by solving the system of equations
c = 2a
a = b - 5
a + b + c = 33
we find
a = 7 cm
b = 12 cm
c = 14 cm

the lengths of the sides of the triangle are 7 cm, 12 cm and 14 cm.
