So hmm notice the picture below
all you really have, is one square, one rectangle, a semi-circle and one trapezoid on the far bottom-left
notice the semi-circle's radius, is just 1 1/2 of a unit
get the area of a circle with that radius, then half it, that's the area of the semi-circle
keep in mind, each block unit there, is 5 feet, so 1 1/2 is just 5 + half 5 or 2.5 or 7.5
now, to get the area of the trapezoid
