The dimensions of load area 1 are 4’x3.25′ and equals 13 square feet. The dimensions of load area 2 are 6’x3.25′ and equals 19.5 square feet. And since the deck is symmetrical, the load areas 5 and 6 on the opposite side of the deck are identical. This leaves the load areas 3 and 4 in the center area of the deck to be determined.
