Each rule represents a geometric sequence. If the given rule is recursive, write it as an explicit rule. If the rule is explicit, write it as a recursive rule. Assume that f(1) is the first term in the sequence. f(n)=11(2)n-1

The shape of the sports field is a rectangle, so the area of the sports field is found by using the rectangle area formula: 

                                         .

We know the Area (6,450.35 square yards), and the length (90.85 yards). Substituting these in the formula we have:

                            .

Thus,  (yards).

71 yards
