Homework Statement
the perimeter of a rectangle is 24 ft. the length is 4 ft longer than the width find the dimensions
width x
length x+4
however, I should be doing it like this:
a first equation should start like: 2x+2y=?
and the second should start like x=y+?
so what's the length and the width?
Homework Equations
The Attempt at a Solution
x + x + (x+4)+(x+4) = 24
4x+8=24
-8 -8
4x = 16
4x/4 = 16/4
x = 4
so width 4 ft
and length 4+4, so 8 ft.
makes sense, since length should be greater than width.
