Lower primary school mathematics question LPQ65

3 identical squares each of sides 8 cm are placed overlapping as shown below. The bottom corners of the top square are at the centres of the other two squares. And all the lines meet at right angles. Find the area of the figure.






           All the three squares are identical with length of 8cm

            The green square overlapped by two orange squares                                                  

             The area of green square not overlapped = 8 × 8 ÷ 2 = 32cm2

             The area of the two orange squares = 2 × 8 × 8 = 128cm2

             The total area of the figure = 32 + 128 = 160cm2
