Two rectangles F and G, not drawn to scale, overlap at H. H is the shaded area which is
16 of Rectangle F and
19 of Rectangle G. If the length of Rectangle F is 6 m and its breadth is 2 m, what is the area of the unshaded part of rectangles F and G?

The overlapping shaded part of rectangles F and G is the same.
Area of Rectangle F
= 6 x 2
= 12 m
2 Area of Rectangle F = 6 u
Area of Rectangle G = 9 u
6 u = 12
1 u = 12 ÷ 6 = 2
Area of unshaded parts of rectangles F and G
= 5 u + 8 u
= 13 u
= 13 x 2
= 26 m
2 Answer(s): 26 m
