Zad 1.
Podstawa to trójkąt prostokątny, więc jego pole wyliczamy z boków 16cm i 9cm.
a = 16cm
b = 9cm
c = 25cm
H = 12cm
Pp = 1/2 * a * b
Pp = 1/2 * 16 * 9 = 72cm²
Ppc = 2 * Pp + a * H + b * H + c * H
Ppc = 2 * 72 + 16 * 12 + 9 * 12 + 25 * 12 = 144 + 192 + 108 + 300 = 744cm²
Zad. 2
a)
a = 7cm
H = 13cm
Ppc = 2 * a² + 4 * a * H
Ppc = 2 * 49 + 4 * 7 * 13 = 98 + 364 = 462cm²
b)
a = 3cm
b = 5cm
H = 14cm
Ppc = 2 * a * b + 2 * a * H + 2 * b * H
Ppc = 2 * 3 * 5 + 2 * 3 * 14 + 2 * 5 * 14 = 30 + 84 + 140 = 254cm²
