The figure, not drawn to scale, is made up of 2 identical rectangles, CDEF and GHJK. Each rectangle has an area of 44 cm². Point G is the centre of rectangle CDEF.
- What fraction of the figure is shaded?
- What is the area of the unshaded parts?
(a)
If we pivot the rectangle GHJK from point G, we can see that the shaded area is
14 of rectangle GHJK.
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 44
= 11 cm
2 Area of the unshaded parts
= 6 x 11
= 66 cm
2 Answer(s): (a)
17; (b) 66 cm
