Did i do everything right on the binder paper?

Your first answer is wrong for the Garden
9 is the length from the walkway to the garden, your equation should be :

A=6(3)
A=18

this means you'd have to add all the numbers again :
18 + 40 + 24=82

all your other answers are correct

hope this helped
