The area of the rectangle is 3800mm and the length of one of the sides is 50mm, calculate the perimeter

The area of the rectangle is 3800mm and the length of one of the sides is 50mm, calculate the perimeter of the rectangle and write down the formula for the area of the rectangle.

A rectangle is a rectangle with equal opposite sides and right angles.

Its area corresponds to the formula:

S = a * b, provided that it is 3800 mm², and the width is 50 mm, we find the unknown side of this figure:

b = S: a = 3800: 50 = 76 mm.

The perimeter or sum of all sides is calculated using the formula:

P = 2a + 2b = 2 * 50 + 2 * 76 = 100 + 152 = 252 mm.
