Ask the student a question, and give any hints about how they should answer this part.

Calculate the maximum possible perimeter of the court.

Round to 2 decimal places!!

Unnamed gapm

Advice

When rounding off a number the maximum value of the decimals can be before rounding up to the next number is "0.499999999", or approximately "0.5"

For example, the maximum the following numbers could be are;

$\var{num1}m = \var{res1}$ m

$\var{num2}m = \var{res2}$ m

Part 1:

The maximum perimeter the court can be is:

$(\var{res1} \times 2) + (\var{res2} \times 2) = \var{ans2}m$

Part 2:

The maximum area the court can be is:

$\var{res1}\times \var{res2} = \var{ans1}m^2$
