To verify whether your brother's claim is valid or not, we need to calculate the total length of the fencing required for the given plot.

Given lengths:

  • Plot length 1: 159 m
  • Plot length 2: 135 m
  • Plot length 3: 396 m

The total length of fencing required is the sum of the lengths of all three sides:

Total fencing required = Plot length 1 + Plot length 2 + Plot length 3

Total fencing required = 159 m + 135 m + 396 m

Total fencing required = 690 m

Your brother claims that 1,000 m of wiring fence is needed. Comparing this to the calculated required length of 690 m:

  • Required fencing: 690 m
  • Brother's claim: 1,000 m

Since the required length is less than your brother's claim, it seems that your brother's claim is valid. The plot can be fenced using 1,000 m of wiring fence with some length left over.
