Question

Kak tlong yg 26 dan 29 donk

makasih​

sm caranya yh

Answer 1

no.29

rumus : Luas = p × l × t

= 24 × 8 × 12

= 2.304

= 2.304 ÷ 2

= 1.152 cm²

Answer 2

26) Lpersegipanjang = p×l = 25×18 = 450 cm^2

Ltrapesium = (25+35)×12/2 = 60×6 = 360 cm^2

Lbangundatar = Lpersegipanjang + Ltrapesium = 450 cm^2 + 360 cm^2 = 810 cm^2

29) Lp = 2(pl+pt+lt) = 2[(24×12)+(24×8)+(12×8)] = 2(288+192+96) = 2×576 = 1152 cm^2
