Answer:
see the explanation
Explanation:
we know that
The perimeter of rectangle is given by the formula

where
L is the length
W is the width
In this problem we have

substitute

simplify

so
The side lengths of the rectangle could be any pair of values whose sum must equal 161 yards
see the attached figure to better understand the problem
With the given height approximate the length of the rectangle

Convert to yards

so

Find the width

therefore
The side lengths of the rectangle could be 48 yd by 113 yd
