tolongin besok di kumpul Ok trmakasih no 1 dan 2

Nomor 1
EFGH = 136cm2
DCGH = 170cm2
BC = AD = EH = FD = 8cm

EFGH = FG x GH
136 = 8 x GH
136/8 = GH
GH = 17

DCGH = GH x CG
170 = 17x CG
170/17 = CG
CG = 10

Luas BCGH = BC x CG
BCGH = 8 x 10
BCGH = 80cm2

Nomor 2
PQRS karena sisi PQRS berhadapan dengan sisi TUVW
