Tolong kerjain yg bagian D nya aja pake cara ya.....

TU = akar (TO2+OU2) = akar ( 8^2 + 6^2) = akar (64 + 36) = akar 100 =10
TV = akar (TO2 + OV2) = akar (8^2 + 3^2) = akar(64 + 9) = akar 73 = 8,54
L alas = p.l = 12 . 6 = 72 cm^2
L permukaan = L alas + L sisi tegak L sisi tegak = 2. 1/2 alas . t = 2. 1/2. 6. 10 =2. 30 =60 L sisi tegak =2. 1/2. alas . t = 2.1/2.12. akar 73 =12 . 8,54 = 102,48 L permukaan = 72 + 60 + 102,48 = 234,48
= akar ( 8^2 + 6^2)
= akar (64 + 36)
= akar 100
=10
TV = akar (TO2 + OV2)
= akar (8^2 + 3^2)
= akar(64 + 9)
= akar 73
= 8,54
L alas = p.l = 12 . 6 = 72 cm^2
L permukaan = L alas + L sisi tegak
L sisi tegak = 2. 1/2 alas . t
= 2. 1/2. 6. 10
=2. 30
=60
L sisi tegak =2. 1/2. alas . t
= 2.1/2.12. akar 73
=12 . 8,54
= 102,48
L permukaan = 72 + 60 + 102,48
= 234,48
