Let the second side be equal to x

Then the first side is x-5

The third side will be x-5-2 = x-7

Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42

3x=44
X= 44/3

Therefore the second sides length is 44/3

The first sides length is 44/3 -5 = 29/3

The third side is 44/3 -7 = 23/3
