How to find the perimeter of this question or the formula that i should use

2 * (48 + 52) = 200

The perimeter of the parallelogram is 200!

200

Step-by-step explanation:

Perimeter of the given parallelogram = 2(a+b)

                                                              = 2·(52+48) = 200

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
