the side of the square board is 50 cm.
that means the perimeter is 4 * 50 = 200 cm.
the drawing in her notebook will have a perimeter of 50 cm.
the scale sill be 50:200 = 1:4.
1 cm in her notebook equals 4 cm in real life.
each side of the square board in her notebook will be 1/4 * the side in real life.
each side of the drawing of the square board in her notebook will be 12.5 cm.
