The length of the rectangle is 50 cm, the perimeter of the rectangle is 2 m, how much the width will be.

Let’s express the length of this rectangle in meters.

According to the condition of the problem, the length of this rectangle is 50 cm.

There are 100 centimeters in one meter, therefore, the length of this rectangle in meters is:

50 cm = 50/100 m = 5/10 m = 0.5 m.

Let’s find the width of the given rectangle.

Let us denote it by x.

According to the condition of the problem, the perimeter of this rectangle is 2 m, therefore, we can draw up the following equation:

2 * (0.5 + x) = 2.

We solve the resulting equation:

0.5 + x = 2/2;

0.5 + x = 1;

x = 1 – 0.5;

x = 0.5 m.

Answer: The width of this rectangle is 0.5 m.
