15.3 units

20.4 units

30.6 units

52.0 units

The perimeter of the rectangle shown on the coordinate plane of points (-6,4), (-7,-1), (3,-3) and (4,2) is 30.6 units. The length of one side of the rectangle is 5.10 units and the other side is 10.20 units. To calculate the perimeter of a rectangle 2L+2W= 30.6 units.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
