bonjour
P (x) = 3 x + 5 x + 4 x = 12 x
P du triangle = 12 x
A (x) = ( 3 x * 4 x ) /2 = 12 x² /2 = 6 x²
Aire = 6 x²
P(x) = 2*π* x = 2πx
P cercle = 2 πx
A (x) = πx²
aire cercle = π x²
P (x) = 2 ( 2 + 3 x + 2 ) = 4 + 6 x + 4 = 6 x + 8
P rectangle vert = 6 x + 8
A (x) = 2 ( 3 x + 2 ) = 6 x + 4
p (x) = 2 ( 3 x + 4 x + 3 ) = 6 x + 8 x + 6 = 14 x + 6
A (x) = 3 x ( 4 x + 3)= 12 x² + 9 x
