A rectangular field has a PERIMETER of 194 feet.
The length is 7 feet more than four times the width. What is the length and what is the width?
~~~~~~~~~~~~~~

W = width L = 4W + 7 (the length) Equation W + (4W + 7) = 194/2 5W + 7 = 97 5W = 97 - 7 5W = 90 W = 90/5 = 18. ANSWER. The width is 18 feet; the length is 4*18 + 7 = 79 feet. CHECK. 18 + 79 + 18 + 79 = 194 feet, the perimeter. ! Correct !

Solved, answered, checked and explained.
