I would choose the formula D (distance to the finish line)=3-2x/2 where x is the distance run so for example for x = 1 km then 2 times 1 = 2/2=1 so D=3-1=2km which is seen to be the logical answer so it seems to corroborate the equation.

Answer:

$(a)\ Area = 13.0695$

$(b)\ Area = 26.139$

Step-by-step explanation:

Given

The attached image

Solving (a): The area (one side up)

This is calculated as:

Area= Area of semicircle + Area of rectangle

So, we have:

$Area = \pi r^2 + l *w$

Where:

$l,w =2,3$ --- the rectangle dimension

$d = 3$ --- the diameter of the semicircle

So, we have:

$Area = \pi * (3/2)^2 + 2 * 3$

$Area = \pi * 2.25 + 6$

$Area = 2.25\pi + 6$

$Area = 2.25*3.142 + 6$

$Area = 13.0695$

Solving (b): Area when both leaves are up.

Simply multiply the area in (a) by 2

$Area = 2 * 13.0695$

$Area = 26.139$
