K - коэффициент подобия
k =(14+42)/108 = 56/108 = 14/27
k = P₁/P₂
14/27 = (14+40+42)/P₂
14/27 = 96/P₂
7/27 = 48/P₂
P₂ = 48*27/7 =1296/7 см
------------
k = 8/5
S₁/S₂ = k² = 64/25 = 64x/25x
S₁ - S₂ = 64x - 25x = 156
39x = 156
x = 4
S₁ = 64x = 256 cm²
S₂ = 25x = 100 cm²

биссектриса делит гипотенузу пропорционально катетам
a/b = 20/15
a = b*4/3
По теореме Пифагора гипотенуза
c² = a² + b²
(20+15)² = (b*4/3)² + b²
35² = b²(16/9 + 1)
35² = b²*25/9
7² = b²/9
b² = 7²*3²
b = 7*3 = 21 см
a = b*4/3 = 28 см
P = a+b+c = 21 + 28 + 35 = 84 cm
