we gots a square and a quarter circle
so area=square+(1/4)circle
area square=side^2
area circle=pir^2
we know that the square side is the circle's radius
side=4=radius
square=4^2=16
circle=pi4^2=16pi, but we got a quarter circle so times 1/4
16pi times 1/4=4pi
add them
square+quatercircle=16+4pi=16+12.56=28.56
first option is correct
