Question 209636
To find the area of the rectangle, you need to know the length (L) and width (W) of the rectangle.
These are given as the diameters of the eight circles.
The radius of each circle is 3 so the diameter is 6.
Assuming the circles are tightly packed, then the diameters of the four cirles on top add up to be the length (L) of the rectangle while the two circles on the side will give you the width (W) of the rectangle.
The length is thus 4 X 6 = 24 and the width is 2 X 6 = 12.
A = L*W
A = 24*12
A = 288 square units.
