Question

One side of triangle is one-third the longest side. the third side is 11 11 feet less than the longest side. the perimeter is 73 73. find all three sides.

Answer 1

Let x represent the longest side. Then the perimeter is
.. x + (1/3)x +(x -11) = 73
.. (2 1/3)x = 84 . . . . . . . . . . collect terms, add 11
.. x = 84*(3/7) = 36

The sides are 36, 12, 25.
