The answer is x=6 and y=4.
6+4=10
and 8 times 6 + 12 times 4 is 96.
I believe it is -8y + 5x - 3
Let's assume
shorter side as x
so, first side =2x
third side =x+19
now, we can find perimeter of triangle
perimeter of any triangle is
first side + shortest side + third side
so, we get

we are given perimeter=187
so, we can set it to 187
and then solve for x





so,
shortest length is x=42 feet
First side =2x=2*42=84feet
third side =x+19=42+19=61 feet
so, dimensions are
first side is 42 feet
second side is 84 feet
third side is 61 feet................Answer
