Answer:
Length = 22 feet Width= 8.5 feet
Step-by-step explanation:
Perimeter= 61
Let Width= x
Length= 2x+5
Perimeter= 2l + 2w
61= 2(2x+5) + 2x
61 = 2(2x+5+x)
61/2 = 3x+5
30.5 -5 = 3x
25.5 = 3x
25.5/3 =x
x= 8.5
Hence, width = 8.5 feet
Then, the length = 2x+5 = 2(8.5) +5 = 22 feet
Hope this helps!
In order to have the variable by itself you have to add 20 to both sides. So your answer would be a=b+20. I hope this helps love! :)
