Given data:
The gieven length of the rectangle in erms of width is L=3w.
The perimeter of rectangel is P=274 feet.
The expressio for the perimeter of the rectangle is,
P=2(L+w)
Substitute the given values in the above expression.
274 feet=2(3w+w)
274 feet=8w
w=34.25 feet.
The length of the rectangle is,
L=3(34.25 feet)
=102.75 feet.
Thus, the width is 34.25 feet and lenth of rectangle is 102.75 feet.
