The area of a playground is 221 yd2. The width of the playground is 4 yd longer than its length. Find the length and width of the playground.
(Hint: Include correct units in your final answer.)
Area = L * W
W = L + 4
Substitute L + 4 for W in the first equation to find L. Put that value in the second equation to find W. to Check, put both values into the first equation.
