The perimeter of the rectangle is 800mm, the length of the rectangle is 252mm, which is the width

The perimeter of the rectangle is 800mm, the length of the rectangle is 252mm, which is the width of the rectangle, how much less than the length.

The perimeter of a rectangle is the sum of all its sides, it is calculated by the formula:

P = 2a + 2b. Let’s find the width of the rectangle, based on this formula, provided that the perimeter is 800 mm and the length is 252 mm:

2 * 252 + 2b = 800,

504 + 2b = 800,

2b = 800 – 504 = 296,

b = 296: 2 = 148 cm is the width of the rectangle.

We find out how much it is cm less than the length:

252 – 148 = 104 cm.
