Answer:
width = 11.75 feet and length is 18.75 feet
Step-by-step explanation:
The length of the fenced-in area is to be 7 feet greater than the width, and the total amount of fencing to be used is 61 feet.
Let w be the width of the rectangle
length is 7 feet greater than the width. so length is w+7
Total amount of fencing is 61 feet. Perimeter = 61 feet
[tex]perimeter = 2(length )+ 2(width)61=2(w+7)+2w\\61=2w+14+2w\\61=4w+14[/tex]
subtract 14 from both sides
[tex]4w=47\\w=11.75[/tex]
width = 11.75 feet and length is 11.75+7=18.75
