Answer 6

"The length of a rectangle is 3 more inches than the width..."
if \(l\) is length and \(w\) is width;\[l=3+w\]

"...the perimeter of the rectangle is 54 inches"
perimeter is \(2l+2w\), so\[2l+2w=54\]
now we translate together by plugging in the length expression for \(l\) (substitution):\[2(3+w)+2w=54\]and simplify...\[6+2w+2w=54\]\[4w=54-6\]\[4w=48\]\[w=48\div4=12\]your width is \(\color{red}{12}\) inches.

to find length: add 3 to the width, like the equation...\[l=3+\color{red}{12}=15\] 15 inches.
