You are creating a garden whose length needs to be 5 feet less than its width and has an area of 84m^2. . What should the dimensions be?
a) Write the length in terms of its width (use w for width).
l=
b) Write an equation that is used to solve for w.
a) The length in terms of its width can be written as l = w - 5.
b) The equation that can be used to solve for w can be derived from the given information that the area of the garden is 84m^2. The area of a rectangle is given by the formula A = length x width. Therefore, we can write the equation as:
84 = (w - 5)w
