Odpowiedź:
a = 6 cm
b = 5 cm
h = 4 cm
H = 7 cm
Pp = a · h = 6 cm · 4 cm = 24 cm²
P₁ = b · H = 5 cm · 7 cm = 35 cm²
P₂ = a · H = 6 cm · 7 cm = 42 cm²
P₃ = b · H = 5 cm · 7 cm = 35 cm²
P₄ = a · H = 6 cm · 7 cm = 42 cm²
Pb = 2 · 35 cm² + 2 · 42 cm² = 70 cm² + 84 cm² = 154 cm²
Pc = 2 · Pp + Pb
Pc = 2 · 24 cm² + 154 cm² = 48 cm² + 154 cm² = 202 cm²
