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).
b) Write an equation that is used to solve for w.
a) The length can be written in terms of its width as:
Length = Width - 5 feet
b) We are given that the area of the garden is 84m^2. Since area = length * width, we can write the equation as:
Area = Length * Width
84m^2 = (Width - 5 feet) * Width
