Question

An architect drew a scaled down plan of a building. On the map, the dimensions of a room are written as 5cm $\times$ 4cm.

If the scale used by him is, 2cm = 10 m. What will be the equivalent ratio of the length and breadth of the actual room.

Answer 1

Given : 2 cm = 10m

$\Rightarrow$ 1 cm is equivalent to 5 m.

Actual dimensions of the room = (5$\times$5) m $\times$ (4$\times$5) m = 25 m $\times$ 20 m$\left[1mark\right]$

$\therefore$Equivalent Ratio between the length and the breadth of the actual room = 25 : 20$\left[1mark\right]$
