The figure, not drawn to scale, is made up of 2 identical squares, JKLM and NPQR. The length of each square is 44 cm. Point N is the centre of square JKLM.
- What fraction of the figure is shaded?
- What is the area of the unshaded parts?
(a)
If we pivot the square NPQR from point N, we can see that the shaded area is
14 of square NPQR.
Fraction of the figure that is shaded =
17 (b)
Fraction of the figure that is unshaded
= 1 -
17 =
67 Area of each square
= 44 x 44
= 1936 cm
2 Area of the shaded part
=
14 x 1936
= 484 cm
2 Area of the unshaded parts
= 6 x 484
= 2904 cm
2 Answer(s): (a)
17; (b) 2904 cm
