The Phytagorean Theorem can be applied!
Let a=x(the length)
____b=x-2(the width)
____c=10
Thus,
By the quadratic formula,
We will eliminate the part 'coz it will be only negative---an impossible result
Continuing,
Thus, the length is 8.2801098892805 units long
If x=8.2801098892805, then x+2=10.2801098892805
Thus, the width is 10.2801098892805 units long
