The length of the rectangle is 5 times its width. Find out what the length is if its width

The length of the rectangle is 5 times its width. Find out what the length is if its width is -2cm3mm. Calculate the perimeter of such a rectangle.

Let’s translate everything into one value.

2 centimeters 3 millimeters = 2 * 10 + 3 = 23 millimeters.

We find out how many millimeters the length of this figure becomes, increasing its width by five times.

1) 23 mm * 5 times = 115 mm – the length of the rectangle.

Now let’s subtract the perimeter of the specified figure if we add all four sides of this figure one by one. Let us denote the perimeter by a capital R.

P = 115 mm + 115 mm + 23 mm + 23 mm = 230 mm + 46 mm = 276 mm.

Or, let’s define the perimeter in 2 ways:

P = 115 mm * 2 + 23 mm * 2 = 276 mm.
