Answer:
The dimension of dog run are 15 feet length and 8 feet width.
Step-by-step explanation:
Given:
Jimmy made rectangular fencing of 46 feet.
Hence we can say Perimeter of rectangle = 46 feet.
Let the width(w) be x.
Also Given he wants length to be 7 feet longer than the width.
Hence Length(l) = [tex]x+7[/tex]
Now we know that Perimeter of rectangle is twice the sum of length and width.
Framing in equation for we get;
Perimeter of rectangle =[tex]2(l+w)[/tex]
[tex]2(x+7+x) = 46\\2(2x+7)=46\\4x+14=46\\4x=46-14\\4x=32\\x=\frac{32}{4}=8\ ft[/tex]
Hence width = 8 ft.
Length = [tex]x+7=8+7=15\ ft[/tex]
Hence the dimension of dog run are 15 feet length and 8 feet width.
