Question

A farmer builds a rectangular pen with a perimeter of 116 ft if the rent is 5 feet more than the width what is the width

Answer 1

The area is 116, so we can plug that in for A. Now, we cant solve the equation yet because it still has two variables. Since we know the length is 5 feet greater than the width, we can rewrite l in terms of w. So this is how the new equation would look like

116=2(w+5)+2w

Answer:
116=2w+10+2w
106=4w
w=26.5 ft.
The width is 26.5 ft.
