The figure below is not drawn to scale. It is made up of 2 identical squares, DEFG and PQRS, overlapping each other. The area of each square is 100cm2. Point G is the centre of square PQRS.

a) Find the area of overlapping portion.

b) What fraction of the figure is overlapped? Give your answer in the simplest form.

 

 

 

 

 

Solution:

            Add 2 dotted lines thru centre point G of square PQRS and rotate square DEFG as shown

 

 

 

 

 

            The area of overlapping is a quarter of the square = 100 ÷ 4 = 25cm2
