Question

Which of the following has the maximum shaded area?

• A. $\left(i\right)$
• B. $\left(ii\right)$
• C. $\left(iii\right)$
• D. Can't be determined

Answer 1

The correct option is B $\left(ii\right)$

Area of Figure $\left(i\right)=8\times 1+8\times 2=24m^2$

Area of Figure $\left(ii\right)=10\times 1.5+10.5\times 2+7.5\times 1=43.5m^2$

Area of Figure $\left(iii\right)=9\times 12-7.5\times 10=33m^2$

$\therefore$ Figure $\left(ii\right)$ has Maximum Area.
