You must cover a hole that is elliptical in shape. You measure the major and minor axes and find them to be 6 ft. and 4.5 ft. respectively. If you want a 6 inch overhang around the hole, how much covering will you need? (Round to the tenths place.)

    area of ellipse is πab where a and b are the semi-axes.

    so the area of our expanded ellipse is π(3+.5)(2.25+.5) = 30.2 ft^2
