Draw a rectangle that is 52 mm long and 21 mm shorter in width. Find the perimeter of this rectangle.

Let’s draw a rectangle, the length of which is 52 millimeters, the width is unknown to us, in order to find it, we need to do calculations, for this:

1) 52 – 21 = 31 mm (rectangle width),

Now let’s find the perimeter

P = (52 + 31) * 2 = 83 * 2 = 166mm,

We convert to centimeters, in 1 cm = 10mm, therefore, we divide,

166: 10 = 16.6;

166mm = 16.6cm;

Answer: The length of the rectangle is 52mm, width is 31, P = 166mm, = 16.6 cm.
