The large rectangle is divided into two unequal parts, A and B.
(a) Tick (✓) all the correct statements.
- A : B = 3 : 10
- A : B = 3 : 7
- A is \(\dfrac{3}{10}\) of the large rectangle
- A is \(\dfrac{3}{7}\) of the large rectangle
[2]
(b) The area of Part A is \(18k\).
Write an expression, in terms of \(k\), for the area of Part B.
