Johann has a piece of fabric that is 27 yards long. He cuts off 15 feet. How many feet does he have left?!?!?

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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
