Answer:
Lenght=50 feet.
Width=44 feet.
Step-by-step explanation:
1. He wants the width of his new garden to be 6 less than the length, this can be expressed as following:
[tex]W=L-6[/tex]
Where W is the width L is the length.
2. The perimeter of a rectangle can be calculated with:
[tex]P=2L+2W[/tex]
3. You know the perimeter, therefore, you can substitute [tex]W=L-6[/tex] into the equation of the perimeter and solve for the length:
[tex]2L+2(L-6)=188\\2L+2L-12=188\\4L=200\\L=50[/tex] (The length is 50 feet)
3. Then, the width is:
[tex]W=L-6[/tex]
[tex]W=50-6=44[/tex] (The width is 44 feet)
