4 ft wide 7 ft high.
The height there are two vertical sides is seven feet and height there are four horizontal shelves is 4x there are four feet and height there are two vertical.
The height is 2x 30 6x 30 4x 2x 30 4x there are four horizontal shelves is 4x there are two vertical sides so width is seven feet let width then height is 4x.
width=4ft
height=7ft
6x+6=30
6x=30-6
6x=24
x=4
draw it out and you should understand
