The figure, not drawn to scale, is made up of 2 identical squares, BCDE and FGHJ. The length of each square is 24 cm. Point F is the centre of square BCDE.
- What fraction of the figure is unshaded?
- What is the area of the shaded part?
(a)
If we pivot the square FGHJ from point F, we can see that the shaded area is
14 of square FGHJ.
Fraction of the figure that is shaded =
17 Fraction of the figure that is unshaded
= 1 -
17=
67 (b)
Area of each square
= 24 x 24
= 576 cm
2 Area of the shaded part
=
14 x 576
= 144 cm
2 Answer(s): (a)
