A. 10 ft
B. 20 ft
C. 21 ft
D. 25 ft

Answer 1

There are numerous important information's already given in the question. Based on those information's the answer can be easily determined. From the information's given, we get the coordinates as (-3, -2) and (4, 1). From these co ordinates, we can say that
Height of the rectangle is 3 feet
Length of the rectangle is 7 feet
Then
Perimeter of the rectangle = 2( length + Height)
= 2(7 + 3)
= 2 * 10
= 20 feet
From the above deduction, we can conclude that the correct option is option "B".
