The width of the rectangle is 10 cm, which is 2 cm less than its length. How long is the rectangle?

The task directly indicates how many centimeters the length differs from the width of the rectangle.
It is said that 10 cm is 2 cm less than the length, which means that the length is two cm more than the width.
If we denoted the length value through the variable y, then we would get the following equation:
y = 10 + 2;
And then, after adding up, we get 12 cm.
ANSWER: the length of the rectangle is 12 cm.
