Side A = x/2
Side B = x/3
Side C = x/4
Perimeter = x/2 + x/3 + x/4 = 220
6x + 4x + 3x = 220 x 12
13x = 220 x 12
x = 203.08
A = x/2 = 101.54
B = x/3 = 67.69
C = x/4 = 50.77
S = 220/2 = 110
Area = √[S (S -A) (S -B) (S -C)]
√[110 (110 - 101.54) (110 - 67.69) (110 - 50.77)]
√[110 x (8.46 x 42.31 x 59.23)]
√(110 x 21200.94
√2332103.4
1527.1226 cm²
