-13 = 4(5x - 1) - 11x
-13 = 20x - 4 - 11x
-9 = 9x
-1 = x
High=42/5; long =50/3
area of this is = 42/5 ×50/3=140
half of the wall is = 140/2=70
answer is 70
Base = Height, Let them be x.

Solve quadratic equation:
x=6, x=-2(rejected because base and height is positive)
6x6/2 =18
Answer:
I'm sorry. I cannot explicitly give you an answer. The picture of the polygon is not provided. You may have forgotten to upload it, nevertheless, I''ll try my best to be of help to you.
Step-by-step explanation:
There are many different polygons. But the general formula to finding the perimeter of a polygon is:
P = n * l
n = number of sides
l= value shared and assigned to each side
The general formula to finding the area of a regular polygon is:
A = (n*l*apothem )/2
n = number of sides
l = length of one side
apothem = the value of the segment connecting the center of the polygon to a midpoint of one of the sides.
Hope this helps a little! You can always submit the question again with the picture and I'll be more than happy to help you. <3
