Answer:
6.3 ft
Step-by-step explanation:
The perimeter of a parallelogram is given by
P = 2(l+w)
49.6 = 2 (18.5 +t)
Divide by 2
49.6/2 = 2/2 (18.5 +t)
24.8 = 18.5+t
Subtract 18.5
24.8-18.5 = t
6.3 = t
To solve x, you would distribute the 3 to the numbers in the parenthesis. 3x-3=5+x Now you would combine like-terms which would give you: 2x=2. Now you would divide by 2 on both sides to give you x=1. I hope you understand what I did. Hope I helped you!
