Question 990377
Hi there,
Make the shortest side = 'x'
One side = 2x
Third side = x + 12
Perimeter is the total of the three sides.
x + 2x + (x + 12) = 112
Collect like terms
4x + 12 = 112
4x = 112 - 12
4x = 100
x = 25 feet.
Shortest side = 25 feet
One side = 50 feet
Third side = 37 feet.
25 + 50 + 37 = 112 feet
Hope this helps :-)
