Tolong yaa kaka kaka dibantu

Pada gambar skala satuan = 2 cm

DC= 2x2 = 4cm
FB = 10 cm
AD = 4 x 2 = 8 cm

a. Luas AFCD = AF xAD = 2(2) x (4)(2)= 4 + 8 = 12
b. L. FBEC = FB x FC = (10) x (4x2) = 10x8 = 80
c. L.ABED = AB xAD = 7(2) x 4(2) = 14 x 8 = 112
d. L. ABC = 1/2 (AB xCF) = 1/2 (7)(2)(4)(2)  = 1/2 (14)(8) = 56
