The figure, not drawn to scale, is made up of 2 identical squares, PQRS and TUVW. The length of each square is 6 cm. Point T is the centre of square PQRS.
- What fraction of the figure is unshaded?
- What is the area of the shaded part?
(a)
If we pivot the square TUVW from point T, we can see that the shaded area is
14 of square TUVW.
Fraction of the figure that is shaded =
17 Fraction of the figure that is unshaded
= 1 -
17=
67 (b)
Area of each square
= 6 x 6
= 36 cm
2 Area of the shaded part
=
14 x 36
= 9 cm
2 Answer(s): (a)
67; (b) 9 cm
