let consider the land ABC
area of ABC=330sq.m
let the adjacent side =AB=11m
let the other side =BC
area of =1/2(ABxBC)
330=11BC/2
BC=330x2/11
BC=60m
using Pythagoras theorem
AC²=AB²+BC²..................1)
AC=√AB²+BC²
AC=√11²+60²
AC=√3721
AC=61m
for verification just put the above value in the equation of Pythagoras theorem i.e, equation 1
