let the width by x cm length= (x+2)cm area = (x+2) times (x) = 80
fLength 10cm Width 8 cm Area = Length x Width 80cm(cubed) = 10cm x 8cm
\[(x+2) \times x = 80\] \[x ^{2} + 2x-80 = 0\]
solve the equation and get x
or you could do trial and error like fosterthepeople

but that would be hard for a larger area in another similar question
how did you get 80?
80 is the area
length x breadth = area
did you see how i did it up there?
