The coordinates of the vertices of a regular polygon are given. find the area of the polygon to the nearest tenth.
a(0, 0), b(2, -2), c(0, -4), d(-2, -2)

The area is equal to

Step-by-step explanation:

we have

A(0, 0), B(2, -2), C(0, -4), D(-2, -2)

Plot the figure

The figure is a square (remember that a regular polygon has equal sides and equal internal angles)

see the attached figure

The area of the square is

Find the distance AB

the formula to calculate the distance between two points is equal to

substitute the values

Find the area of the square

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
