As you can see, the area of the scarf is equal to the area of the rectangle minus the area of the 2 semi-circles (which form a circle)

Now, we calculate the area of the rectangle : 28 x 15 = 420 in2

The diameter of the circle is 15in -> The radius = 15 : 2 = 7.5in.

We now find the area of the 2 semi-circles : 7.5 x 7.5 x 3.14 = 176.625 in2

So, the area of the scarf is : 420 - 176.625 = 243.375 in2
