Q2: 160 + 120 + 210 + 70 + 90 + 90 = <em><u>740</u></em>

Q3:  (160 x 120) + (70 x 90) = <u><em>25500</em></u>

          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 = <em><u>140.54cm^2</u></em>

<em><u></u></em>

Q6: 11 + 9 + 20 + 14 = <em><u>54</u></em>

Q7: 9 x 11 = 99

11 x 11 = 122 / 2 = 61         99 + 61 =<em><u> 160^2</u></em>
