x = length
y = width
Perimeter = 2x+2y
24 = 2x+2y
x = y + 2 Since the length is two feet longer than the width.
Use substitution to solve:
2(y+2) +2y = 24
the primeter of a rectangle is 24ft. the length is 2 ft longer than the width. Find the dimensions. Write a system of linear equations and solve the resulting system. Let x be the length and y be the width,
write the first equation.
2x+2y=__
write the second equation.
x=y+__
what is the length?
what is the with?
Please help!!

okay. I came up with 14ft for the length and 10ft for the width.
correction length is 8ft and width is 4 ft.
