**Answer This Question**

Help needed.

Subtract the area of the inner circle from the area of square WXYZ to get the area of the 4 corners.

Each is equal to A. So divide by 4 to get your answer.

b)

Draw a straight line from X to Z, and from W to Y. Now square WXYZ is divided into 4 equal triangles. The area of each triangle is just ¼ of the area of the square.

Notice that areas B and C can be combined to form a triangle. This triangle is identical to each of the 4 triangles , and has the same area.

Final answers for a) and b) are 3.43cm² and 19.43cm² respectively , correct to two decimal places.
