The figure, not drawn to scale, is made up of 2 identical squares, RSTU and VWXY. The length of each square is 13 cm. Point V is the centre of square RSTU.
- What fraction of the figure is unshaded?
- What is the area of the shaded part?
(a)
If we pivot the square VWXY from point V, we can see that the shaded area is
14 of square VWXY.
Fraction of the figure that is shaded =
17 Fraction of the figure that is unshaded
= 1 -
17=
67 (b)
Area of each square
= 13 x 13
= 169 cm
2 Area of the shaded part
=
14 x 169
= 42.25 cm
2 Answer(s): (a)
67; (b) 42.25 cm
