So they're all congruent? They're all tangent to their adjacent circles and to the rectangle?

|dw:1333159035310:dw| Radii of same or congruent circles =. That lets me draw the picture above. Then, the area of the rectangle is 18 * 6 = 108yd². The area of a circle is πr² = π * 3² = 9π. There are three of them, so the area of the circles is 3*9π = 27π. Assuming the shaded region is everything except the circles... SR (shaded region) = whole thing - non shaded part Whole thing is the rectangle. Part is the circles. 108 - 27π yds² is your answer. Using 3.14 for pi, SR approx = 23.22 yd²
