The figure, not drawn to scale, is made up of 2 identical rectangles, RSTU and VWXY. Each rectangle has an area of 28 cm². Point V is the centre of rectangle RSTU.
- What fraction of the figure is shaded?
- What is the area of the unshaded parts?
(a)
If we pivot the rectangle VWXY from point V, we can see that the shaded area is
14 of rectangle VWXY.
Fraction of the figure that is shaded =
17 (b)
Fraction of the figure that is unshaded
= 1 -
17 =
67 Area of the shaded part
=
14 x 28
= 7 cm
2 Area of the unshaded parts
= 6 x 7
= 42 cm
2 Answer(s): (a)
17; (b) 42 cm
