tolong nomer 5 sama 6 ya kak

5. a) BC² = 48²+36²
BC² = 2304+1296
BC = √3600 = 60

AB=BC=60

CD² = 64²+48²
CD² = 4096+2304
CD = √6400 = 80

AD=CD=80

k=60×2+80×2=280 cm

b) d1×d2×½
= (48×2)×(36+64)×½
= 48×100
= 4800 cm³

6. Lkertas = 120×150 = 18000
Llayanglayang = 40×50×½ = 1000

Lkertas-Llayanglayang = 18000-1000 = 17000 cm²

maap kalo kurang tepat
kalo benar tolong dilike dan jadiin jawaban terbaik! oke

nomor 5nya ajha..maaf
