Q.13 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.
Breadth of the hall (in metres) $$\rightarrow 10 \square 40$$
Length of the hall (in metres) $$\rightarrow 25 50 \square$$
$$\frac{Breadth}{length} = \frac{\square }{50} = \frac{2}{5}$$
Breadth =$$\frac{(50 × 2)}{5} = 20 m$$
$$\frac{breadth}{length} = \frac{40}{Length} = \frac{2}{5}$$
Length =$$\frac{(40 × 5)}{2} = 100$$
