Dimensions:
Length = 13.256m
width = 9.256m
Step-by-step explanation:
Let the length of the sandbox be = l and its width be = w
The length of the sandbox is 4 ft more than the width.
This means that ----- equation 1
For the next step, we will be assuming that the strip of grass is a perfect rectangle. The length of the grass strip will be equals to the length of the sandbox.
Area of the grass = length X width = ------ equation 2
The total area for the sandbox and the grass is 189 square feet.
This means that
<em>(Kindly note that the positive value for the width was chosen as length cannot be negative).</em>
Now that we have our width, we can put this into equation 1 to get the length.
