The formula to get the surface area of a rectangle is length x width (l x w). In order to solve, we need to gather the given first, which is 18 m (length) and 9 m (width). When you have succeeded on finding the two given, you may now fill up the formula then solve the equation.
(rectangle: A= length x width)
x 9 A= 162m^2 (squared)
really you have more ok what
