Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in 2.) Be sure to use the same units for all measurements This is because, a semi-circle is just the half of a circle and hence the area of a semi-circle is the area of a circle divided by 2. The area of a semi-circle with radius r, is (πr 2 )/2. π is a constant which is approximately 3.14 or 22/7 ASSUME it is the radius of the inscribed circle; in other words it is the width from one side of the octagon to its opposite. a.
