The width of the rectangle is 10 cm, which is 2 times less than its length. What is the length of the rectangle.

Let’s find the value of the length of the rectangle given to us, for this we need to multiply the specified value of the width of the rectangle given to us by two:

10 * 2 = 20 cm – this is the value of the length of the rectangle given to us;

Let’s find the value of the perimeter of the rectangle given to us, for this it is necessary to add the specified value of the width of this rectangle to the found value of the length of this rectangle and multiply the result by two:

(10 + 20) * 2 = 60 cm – this is the value of the perimeter of the rectangle given to us.
