Consider the statement: Ratio of breadth and length of a hall is 2: 5. Complete the following table that shows some possible breadths and lengths of the hall.

Solution:

(i) Length = 50 m

2 / 5 = Breadth / 50

Using cross multiplication

50 × 2 = 5 × Breadth

Breadth = (50 × 2) / 5

= 100 / 5

= 20 m

(ii) Breadth = 40 m

2 / 5 = 40 / Length

Using cross multiplication

40 × 5 = 2 × Length

Length = (40 × 5) / 2

Length = 200 / 2

Length = 100 m

Therefore, the breadth in the second column is 20 m, and the length in the third column is 100 m.
