Square A + Rectangle B before overlapping = 23 units
unshaded area = 17 units

Realise that unshaded area + 2 shaded area = Square A + Rectangle B

17 units + 2 shaded area = 23 units

2 shaded area = 23 units - 17 units
= 6 units

1 shaded area = 6 units ÷ 2 = 3 units

Ratio of shaded area to Square A + Rectangle B before overlapping = 3 : 23

Not correct. 48cm² is two x the shaded area
