given :-
sides of the triangular plot :-
a = 80cm
b = 120cm
c = 50cm
therefore it's semi-perimeter = (80 + 120 + 50)/2
= 250/2
= 125m
area of the triangular plot by heron's formula = √s(s - a)(s - b)(s - c)
= √125(125 - 80)(125 - 120)(125 - 50)
= √(125 × 45 × 5 × 75)
= √2109375
= 5 × 5 × 5 × 3√15
= 375√15cm²
