easy!
In a parallelogram opposite side are congruent.
SEGMENT AB = CD
so
4x+50 = 2X+7
-4x_______-7
43 = -2x
_____/-2
x = -21.5
plug it IN
AB[4(21.5)+50)
=== 86+50
= 136 multiply it by 2 because primeter u have to add up all the sides so and AB = DC u can just times it by 2 to get the sum of both.
AB+CD = 272
bc[2(21.5)-3]
== 43 - 3 == 40
times 2 = 80
add then up u get
80+272 =352

4x+50=2x+7
solve for x and then put that number in for all of them
once you find out cd and ab, you double bc's answer and add all together
