luas trapesium = (a + b) x t/2 =(29 + 17) x 17/2 =46 x 17/2 = 391 cm²
(3)
luas JG = a x t
240 = 16 x t
t = 240/16 
t = 15 cm
(4)
luas = d1 x d2/2 = 18 x 25 /2 =9 x 25 =225 cm²
(5)
luas = luas persegi - luas lingkaran 
= s x s - 22/7 x r x r
=28 x 28 - 22/7 x 14 x14
=784 - 616
=168 dm²
(6)
v = luas alas x tinggi
v = 3,14 x r x r x t
v = 3,14 x 20 x 20 x 50
v = 1256 x 50
v = 62.800 dm³
