Perimeter of rectangle is 21.6 unit</h2>
Step-by-step explanation:
Refer the figure, we need to find perimeter of rectangle formed by these points.
Let us use distance formula
Length of rectangle is given by distance from (−4, 3) to (0, −3) and width is given by distance from (−4, 3) to (−1, 5).
Perimeter = 2(Length + width) = 2 x ( 7.21+3.61) = 21.64 unit
Perimeter = 21.6 unit
Perimeter of rectangle is 21.6 unit
