A square is folded in half to form a rectangle. If the resulting rectangle has a perimeter of 15 inches,what is the are of the original square?HELP...please?

  • Math - ,

    15=2(s+(s/2))
    15=2s+s
    15=3s
    s=5in

    A=s^2

    With a little trial and error, I figured that the dimensions of the rectangle are 2.5 by 5

    That means that the original square has 5 inches on each side.

    Take it from there.

  • Math - ,

    15x4=60 or 15x5=75.
    I'm not sure?

    CeCe -- please do not post answers when you don't know! You're just confusing other students.
