what kinda waco scarf is dat?

anyway, it seems to be a rectangle-2 semicircles
well, the 2 semicircles seem to add to 1 circle so

area of circle=pi times radius^2
diameter/2=radius
area of rectangle=length times width


rectnalge-circle=scarf
rectanlge=28 by 15=28*15=420
circle, diameter is 15 so radius is 15/2=7.5
area=pi7.5^2=pi56.25=3.14*56.25=176.625
so
rectangle-circle=420-176.625=243.375 square inches

the area of the scarf is 243.375 square inches
