Question

The side of a square board is $50\mathrm{cm}.$ A student has to draw an image in her notebook. If the drawing of the square board in the notebook has a perimeter of $40\mathrm{cm},$ then by which scale the figure has been drawn?

Answer 1

Finding the Scale of the figure drawn

The side of a square board is $50\mathrm{cm}.$
Perimeter of square board $=4\mathrm{x}\mathrm{side}=4\mathrm{x}50=200\mathrm{cm}$
The drawing of the square board in the notebook has a perimeter of$40\mathrm{cm}$
Scale $=200÷40$
Scale $=5:1$

Hence, the required scale is $=5:1$
