Tolong kerjakan bagian D, E, F Pakai cara

d. Lpersegipjg = p x l = 10 x 5 = 50cm2
Lpersegipjg = p x l = 18 x 5 = 90cm2
Lpersegipjg = p x l = 10 x 8 = 80cm2
Ltotal = 50 + 90 + 80 = 210cm2

e. Lbelahketupat = d1 x d2 x 1/2 = (24:2) x (24:2) x 1/2 = 12 x 12 x 1/2 = 72cm2
Luastrapesium = 1/2 x jmlsisisjjr × t = 1/2 x (24+12) x 16 = 1/2 x 36 x 16 = 288cm2
Ltotal = 72 + 288 = 360cm2
