The figure, not drawn to scale, is made up of 3 identical squares, ABCD, EFGH and JKLE. The length of each square is 44 cm. Point E is the centre of square ABCD.
- What fraction of the figure is unshaded?
- What is the area of the shaded parts?
(a)
If we pivot the square EFGH from point E, we can see that the shaded area is
14 of square EFGH.
Similary, if we pivot the square JKLE from point E, we can see that the shaded area is
14 of square JKLE.
Fraction of the figure that is shaded =
210 =
15 Fraction of the figure that is unshaded
= 1 -
15 =
45 (b)
Area of each square
= 44 x 44
= 1936 cm
2 Area of the shaded parts
= 2 x
14 x 1936
= 968 cm
2 Answer(s): (a)
45; (b) 968 cm
