A square is a quadrilateral with all sides the same length and all
angles being the same size and right angles (90˚). From this
understanding, it is obtained that each angle is divided equally by its
diagonal and the two diagonals intersect perpendicularly.
a. Around Square
Square is a rectangle that is as long as the same length so p = l
because p = l, then the perimeter of the square is k = (2(p + l) = 2(2p)
= 2(2l)
suppose p = l = s, so
K = 4s
with s = square side length
b. Square Area
A square has a lengthy size = width or p = l = s, then the formula for
the area of a square is
L = s x s = s
2
with s = square side length
