Problema Solution
One side of triangle is 2 times the shortest side. The third side is 7 feet more than the shortest side. The perimeter is 59. Find all three sides.
Answer provided by our tutors
let 'x' represent the shortest side, then '2x' represents the second side and 'x+7' represents the third side; we assume all sides are measured in feet
59 = x + 2x + x+7
solving for 'x' we have x=13
2*13 = 26
13+7 = 20
the sides of the triangle are 13, 20 and 26 feet
