Area = width * Length
Length = width + a
________________-
Can you see the updates?
_______________________
In terms of a
136 = width * Length
Length = 136/ width
and
width
replacing the length
136 = width * (width + a)
136 = width ^2 + a* width
width ^2 + a* width = 136
_______________
if a = 9
136 = width * (width + 9)
136 = W
________________--
Can you confirm if it is a or 9?
