1.
a. luas = 1/2 x a x t
= 1/2 x 12 x 8
= 48 cm^2
b. luas = 1/2 x a x t
= 1/2 x 15 x 18
= 135 cm^2
c. luas = 1/2 x a x t
= 1/2 x 26 x 19
= 247 cm^2
d. luas = 1/2 x a x t
= 1/2 x 100 x 400
= 20000 cm^2
e. luas = 1/2 x a x t
= 1/2 x 32 x 29
= 464 cm^2

a. alas = 2 x luas : t
= 2 x 40 : 10
= 8 cm
b. alas = 2 x luas :t
= 2 x 64 : 16
= 8 cm
c. alas = 2 x luas : t
= 2 x 120 : 12
= 20 cm
d alas = 2 x luas : t
= 2 x 125 : 5
= 50 cm
e alas = 2 x luas : t
= 2 x 144 : 16
=18 cm
