Q2: 160 + 120 + 210 + 70 + 90 + 90 = 740

Q3: (160 x 120) + (70 x 90) = 25500

19200 + 6300

Q5: As = 1/2 $\pi$ (6cm)^2

(6cm)^2 = 36cm

1/2 $\pi$ (36)

\pi = 3.14159 x 36 = 113.09 / 2 = 56.54 cm^2 area

12 x 7 = 84 + 56.54 = 140.54cm^2

Q6: 11 + 9 + 20 + 14 = 54

Q7: 9 x 11 = 99

11 x 11 = 122 / 2 = 61 99 + 61 = 160^2
