tolong jawab plissss besok mau di kumpulin. beserta cara

1) Lsegitiga + Ltrapesium
=1/2.20.20 + 1/2.(25+20).12
=200+ 270
=470 cm^2

2) Llayang2 + Ltrapesium
=1/2.20.16 + 1/2.(22+14).15
=160+270
=430 cm^2

3) Lpersegi + Lpersegi panjang
=7.7 + 30.7
=49+210
=259 cm^2

4) Ltrapesium - Llingkaran
=1/2.(26+24).14 - 22/7.7.7
=350-154
=504 cm^2

5) Lsetengah lingkaran + Lsegitiga
=1/2.22/7.7.7 + 1/2.14.4
=77 + 28
=105 dm^2

6) Lpersegi - (Lsegitiga+L1/2Lingkaran)
=20.20 - ( 1/2.20.8 + 1/2.3,14.10.10)
=400- (80+157)
=400 - 237
=163 m^2
