Answer:

Area = 35 ft^2

Step-by-step explanation:

The shortcut for finding area of a regular polygon is:

Area = 1/2 a•s•n

where a is the apothem, that was given and s is the side length (also given) and n is 5 because a pentagon has 5 sides.

A = 1/2 (3.1)(4.5)5

A = 34.875

The directions say to round to the nearest whole.

A = 35 ft^2
