Me solve this equation . y/9 + 5 = 0

y/9 +5 =0

 subtract 5 from each side

y/9 = -5

 multiply both sides by 9

y = -5 * 9

y = -45

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

one set of data has more variation than the other. hope this !
