There is a rectangle with sides 12 cm and 10 cm. How should you measure its length to make a square?

If the sides of the rectangle are 12 cm and 10 cm, then we can change this rectangle so that we get a square.

First, remember that the sides of the square must be equal.

If the smaller side of the rectangle is 10 cm, then you must first measure 10 cm of the second side, and cut off the remaining extra centimeters.

12 cm – 10 cm = 2 cm – must be cut from the side, which is 12 cm.

If both sides of the figure are 10 cm each, then this means that this figure is a square.

Answer: you need to measure the length of the second side and subtract, and then cut off, as many centimeters as it distinguishes one side from the other.
