Solution
The correct option is B 32 units
The four vertices are plotted in the given graph.
Coordinates of vertex A are (-3, 4).
Coordinates of vertex B are (4, 4).
Distance between A and B is the absolute value of the difference in x-coordinates of A and B.
= |-3-4| = 7 units
Coordinates of vertex B are (4, 4).
Coordinates of vertex C are (4, -5).
Distance between B and C is the absolute value of the difference in y-coordinates of B and C.
= |4-(-5)| = 9 units
Perimeter = 2(length+width) = 2(9+7) = 2(16) = 32
Hence, the perimeter = 32 units
