Two rectangles E and F, not drawn to scale, overlap at G. G is the shaded area which is
15 of Rectangle E and
17 of Rectangle F. If the length of Rectangle E is 11 m and its breadth is 5 m, what is the area of the unshaded part of rectangles E and F?

The overlapping shaded part of rectangles E and F is the same.
Area of Rectangle E
= 11 x 5
= 55 m
2 Area of Rectangle E = 5 u
Area of Rectangle F = 7 u
5 u = 55
1 u = 55 ÷ 5 = 11
Area of unshaded parts of rectangles E and F
= 4 u + 6 u
= 10 u
= 10 x 11
= 110 m
2 Answer(s): 110 m
