The formula for the area of a rectangle is ___________.
Using trail and error, if the area is 96m^2, then the length and width are ___________.

Answer 1

An expression for the length of the rectangle in terms of the width would be 2w - 4.
The formula for the area of a rectangle is length times width (A = l * w).
Using trial and error, if the area is 96m^2, then the length and width are 12m and 8m respectively.
