A square is a geometric shape in which all sides are equal and the corners are straight.
Its area corresponds to the formula S = a², and the perimeter: P = 4a.
Let’s find the length of the side of the square, provided that its area is 49 cm²:
a = √49 = 7 cm.
Let us express the side through the perimeter, which = 28 cm:
a = 28: 4 = 7 cm.
