Question

Dijawab yaa pliss dngan cra kerjanya jga

Answer 1

P = 3/9 x 15 = 5cm
l =2/9 x 15 =3,33
t = 5/9 x15 = 6,67
(5 x 3,33 x 2) + (5 x 6,67 x 2) + (3,33 x 6,67 x 2) = 122,2

Answer 2

X = 15/3
x = 5

p = 15cm
l = 2.5 = 10
t = 4.5 = 20

Lp = 2(pl + pt + lt)
Lp = 2(15.10 + 15.20 + 10.20)
Lp = 2(150 + 300 + 200)
Lp = 2.650
Lp = 1300
