How do you find the perimeter of a parallelogram

D

Step-by-step explanation:To find the perimeter of this parallelogram, you would have to find the distance between the coordinates.

I would use the distance formula for this question.

Distance Formula -

Ok, let's find the length of side AB.

Coordinates of A = (-5, -7)  This will be our second x and y coordinates []

Coordinates of B = (2, -3) These will be our first x and y coordinates   []

Now Substitute Into The Equation -

Solve/Simplify -

Now let's solve for side CB

Point C = (-1, 2) This will be our second x and y coordinates []

Point B = (2, -3) These will be our first x and y coordinates   []

Substitute and Solve -

Now solve for the other two sides -

Because this shape is a rectangle, the parallel lines are the same length.

Now, find the perimeter-

Hoped this helped!~

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

b. f(x) = –√x + 3this is the correct answer
