Jawab:
1. a = 14 cm
t = 9 cm
L = [tex]\frac{1}{2}[/tex] x a x t
= [tex]\frac{1}{2}[/tex] x 14 x 9
= 63 (D)
2. p = 28 cm
L = 588 [tex]cm^{2}[/tex]
l = L : p
= 588 : 28
= 21 cm (C)
3. L = 3.025 [tex]m^{2}[/tex]
s = [tex]\sqrt{3.025}[/tex]
= 55 cm
K = 4 x s
= 4 x 55
= 220 (C)
4. a = 65 cm
L = 1.625 [tex]cm^{2}[/tex]
t = [tex]\frac{L}{a}[/tex] x 2
= [tex]\frac{1.625}{65}[/tex] x 2
= 25 x 2
= 50 cm (A)
5. p = 75 m
l = 45 m
biaya = Rp 115.000,00 / m
K = 2 x (p+l)
= 2 x (75 + 45)
= 2 x 120
= 240 m
Biaya = 115.000 x 240
= Rp 27.600.000 (A)
