tolong jawab no 13 dan 14 denagn caranya

ini no. 13 kalo salah maafyaa

13.)t.alas= 8cm (phytagoras 8,15,17)
L.p = (2x L.a) + (k.a x t.p)
L.p = (2(8x15:2)) + ((8+15+17)x20)
= (2x60) + (40x20)
= 120 + 800 = 920cm² (C.)

14.)t.a = 8cm (phtagoras 6,8,10)
k.a = 6+8+10 = 24cm
L.a = 12 x 8 :2 = 48cm²
576 = (2x48) + (24xt)
576 = 96 + 24t
24t = 576 - 96
t= 480 : 24= 20 cm

semoga membantu
