How to find the area of a square: The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height. If a square has a base of length 6 inches its area is 6*6=36 square inches.
The shaded space will have an area equal to the area of the square minus the area of the circle. Let's call the area of the square Q and the area of the circle C. So you're looking for Q-C. You're given the width of the square as 7.haded Area = Area of the Square-Area of the Circle Area of square = 7 x 7 = 49unitsÂ² Area of circle = 3.5Â² x Ï = 12.25Ï unitsÂ² Shaded Area = 49unitsÂ² - 12.25Ï unitsÂ² = 10.52 unitsÂ² Hope that helps. =D.
