Answer
$45$ feet
Work Step by Step
Let $x$ = the length of the garden
RECALL: The area of a rectangle is given by the formula $A=$(length)(width).
Substitute the given area and width into the formula above to have:
$\\A = \text{(length)(width)}
\\1125 = x(25)
\\\frac{1125}{25} = x
\\45 = x$
Thus, the length of the rectangular garden is 45 feet.
