Area of a square = side^2
In this problem,
Side = 5ft
Plug 5 into the formula above
Area = 5^2 = 25ft^2
But we have to subtract the area of the circle.
Area of a circle = πr^2
r = radius
The diameter is 5 ft and the radius of a circle is diameter / 2
The radius of this circle = 2.5
Let's plug that into our formula.
Area = π(2.5)^2 = 19.63.
Let's subtract the area of the circle from the square
25 - 19.63 = 5.37 = 5.4ft^2
