A vertex is a corner
notice, #vertices=#sides
we cannot use a circle since it is 1 side but 0 vertices

square,trapezoid, triangle, pentagon, hexagon, octogon

square+triangle is 4+3=7
next is trapezoid which is 4 sides

the shapes can be
trapezoid, square, triangle or
trapezoid, rhombus, triangle or

PLEASE HELP ASAP, THANK YOU

First step is to plot all the given coordinates in the xy plane.

Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.

Formula to find the area of trapezium is:

Area = \frac{(AD+BC)}{2} *DE

= \frac{4+6}{2} *5

=\frac{10}{2} *5

= 5 * 5

= 25 square units.

So, third choice is correct.

Hope this helps you!
