Question

The vertices of a quadrilateral is shown in the below graph. Find the perimeter of the quadrilateral.

• A. 32 units
• B. 30 units
• C. 22 units
• D. 18 units

Answer 1

The correct option is A 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
