Area of semicircle = 1/2 the area of a circle: [tex] A_{sc}=\frac{1}{2} \pi r^{2} [/tex] radius is half the diameter of 6ft. [tex] A_{sc} = \frac{1}{2} \pi (3^{2} )=14.13 ft^{2} .[/tex] Area of the rectangle: [tex] A_{r} =lw=15*6=90 ft^{2} .[/tex] Add the two together: 90 + 14.13 = 104.13 Round to the nearest tenth (one decimal place) Area = 104.1 square feet.
