Question

An edge of a square has vertices with coordinates (a, b) and (-a,- b). Write expre

in terms of a and b for its perimeter and area.
Perimeter =
units
Area =
square units

Answer 1

Explanation:

Value of the edge of the square=d

`d^2=(a^2+b^2+(-a)^2+(-b)^2=2(a^2+b^2)\\\\d=√(2(a^2+b^2))\\\\Perimeter=4*d=4*√(2(a^2+b^2))\\\\Area=d^2=2(a^2+b^2)\\`
