1 . luas = 1/2 x (a+b) x t = 1/2 x (16+24) x 15 = 1/2 x 40 x 15 = 300 cm^2 4 . luas = 1/2 x d1 x d2 = 1/2 x 18 x 20 = 180 cm^2 8. luas trapesium = 1/2 x (a+b) x t = 1/2 x (18+24) x 12 = 1/2 x 42 x 12 = 252 cm^2 luas layang layang = 1/2 x d1 x d2 = 1/2 x 20 x 24 = 240 cm^2
= 1/2 x (16+24) x 15
= 1/2 x 40 x 15
= 300 cm^2
4 . luas = 1/2 x d1 x d2
= 1/2 x 18 x 20
= 180 cm^2
8. luas trapesium = 1/2 x (a+b) x t
= 1/2 x (18+24) x 12
= 1/2 x 42 x 12
= 252 cm^2
luas layang layang = 1/2 x d1 x d2
= 1/2 x 20 x 24
= 240 cm^2
