Answer:

large box = 3 feet, small box = 1 foot

Explanation:

large box = l

small box = s

3l + 2s = 11

2l + 1s = 7

This is simultaneous equations

so you make the one of the boxes equal

I am going to make the small boxes equal each other

4l + 2s = 14

3l + 2s = 11

Take them both away from each other

1l = 3

put that back into the equation

so s = 1
