The perimeter of a shape is the total measurement of all the edges of a shape.
Perimeter of the square is 460 unit.
Since, coordinates of three vertices of square ABCD are given as A(−212,112), B(−212,−3) and C(2,112).
If coordinate of M(a, b) and N(c, d) are given.
Then by using distance formula,
[tex]MN=\sqrt{(d-b)^{2} +(c-a)^{2} }[/tex]
Similarly, [tex]AB=\sqrt{(-3-112)^{2}+(-212+212)^{2} } \\\\AB=115[/tex]
In square, all four sides are equal.
Perimeter of Square, [tex]=4*side[/tex]
[tex]=4*115=460[/tex] unit.
