Answer:
19.4ft
Explanation:
A parallelogram has two sides parallel and equal meaning the top and bottom length are the same;
Meaning if the top is C, the bottom is C.
Similarly the length at the right side equals that on the left;
That means the the left = 60.4ft
Perimeter means distance round
And perimeter =157.6ft
Meaning if we start from the Top, it means:
C+ 60.4ft + C + 60.4ft= 157.6ft
C + C + 60.4ft+ 60.4ft = 157.6ft
2C + 120.8 = 157.6
2C = 157.6 - 120.8
2C= 36.8
C = 36.8/2
C= 19.4ft
