Answer 2

The height of the column should be 4️⃣ 5 cm.

Given - Height and number of children

Find - Height of column

Solution - Value of 8 unit column = 40 children

Value of 1 unit column = $\frac{40}{8}$

Value of 1 unit column = 5 children

Height representing 5 children = 1 unit

Height representing 25 children = $\frac{1 \times 25}{5}$

Height representing 25 children = 5 units

Hence, height of column should be 4️⃣ 5 cm.
