The rectangle ABCD measures 14 x 7cm. There are two identical sized circles which just touch the sides of the rectangle and the other circle. There is a diagonal BD. What is the total area of the shaded part in the diagram?
49 cm2
Every shaded shape in this diagram has an unshaded shape of equal area.
So the total area of the shaded part in the diagram is ½ × 14 × 7 = 49 cm2.
