Oigure has two parts
The first is a rectangle with width 6ft and length 10ft
This gives has the area of
L*W=10*6=60ft^2
The other part is a semicircle whose area formula is given by
½*pi*radius^2
Area of the semicircle=1/2*3.14*3^2
=14.13ft^2
Then we add the both area
60ft+14.13ft=74.13ft^2
Rounding the above answer to the nearest whole number we get
74ft^2
