The perimeter of the rectangle is 32 m one side is 11 m long what is the length of the missing side

The length of the missing side is 5 m

Step-by-step explanation:

In order to find this, use the perimeter formula.

P = 2L + 2W

Now input 11 as the L and 32 as P

32 = 2(11) + 2W

32 = 22 + 2W

10 = 2W

5 = W

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)
