for this it is a perimeter problem. that means add up the lengths of all of the sides.
imagine a rectangle. one side, the long one, is measured 74 feet. the short side is measured at 42 feet. since there are two of each side you must multiply both 74 and 42 by 2 and add them together.
[tex]74 \times 2 = 148[/tex]
[tex]42 \times 2 = 84[/tex]
148 + 84 = 232
