You don't need the apothem if the side length is known, the area can be expressed as:

A(n,s)=ns^2/(4tan(180/n)), n=number of sides and s=side length so

A(7,28)=(7*28^2)/(4tan(180/7))

A≈2848.987 ft^2

A≈2849 ft^2 (to the nearest tenth of a square foot)

I guess you want to find the average speed for the whole journey

average speed = distance travelled / time

the distance from home to the shop = speed * time = 0.5*10 = 5 miles

time for travelling back = distance / speed = 5/30 = 1/6 hours

average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
