Hi,
Let x represent the shorter leg, then we have:
a right triangle with x & (x+1m) as legs and (x+2m)as the hypotenuse
using the Pythagorean Theorem to solve
x%5E2+%2B+%28x%2B1%29%5E2+=+%28x%2B2%29%5E2
Simplifying
x%5E2+%2B+x%5E2+%2B+2x%2B+1+=+x%5E2%2B+4x+%2B4
x%5E2+%2B+2x%2B+1+=+4x+%2B4
x%5E2+-+2x+-+3+=+0
factoring
(x-3)(x+1)=0
x = -1 cannot use this value
x = 3
Triangular lot has the dimensions 3m , 4m and 5m
check our answer using Pythagoream theorem
9 + 16 = 25
