A rectangle is a rectangle with equal opposite sides and right angles.
Its area is calculated by the formula: S = a * b. Let’s find the unknown side of such a figure, based on this formula, provided that the area is 60 m² and the length is 12 m.
b = S: b = 60: 12 = 5 m.
The perimeter or the sum of all sides is determined by the formula:
P = 2a + 2b = 2 * 12 + 2 * 5 = 24 + 10 = 34 m.
