Find the perimeter and area of a rectangular treadmill if its sides are equal to 2 m 400 m.

From the problem statement, we know that the length of the treadmill is a = 400 meters, and the width is b = 2 meters, respectively. In order to find its perimeter and area, we need to use the following formulas:

Perimeter of the rectangle:

P = 2 * (a + b)

Rectangle area:

S = a * b

Let’s apply these formulas to our parameters.

P = 2 * (a + b) = 2 * (400 + 2) = 2 * 402 = 804 meters

S = a * b = 400 * 2 = 800 square meters.

Thus, we get that the perimeter of the treadmill is 804 meters, and its area is 800 square meters.
