Mohon ya nomor 26 dan 27 pake cara pls ya

Bangun I (persegi)
L = S x S
L = 7 x 7 = 49 cm^2

Bangun II ( trapesium)
L = JSS/2 x t
L = (7+12)/2 x (15 -7 )
L = 19/2 x 8
L = 19 x 4
L = 76 cm^2

Luas = Bangun I + Bangun II
Luas = 49 + 76 = 125 cm^2 ( C )

L permukaan balok = 2 x (p x l + p x t + l x t)
L = 2 x ( 35 x 10 + 35 x 18 + 18 x 10 )
L = 2 x ( 350 + 630 + 180 )
L = 2 x ( 1.160)
L = 2.320 cm^2 (D)
