Find an expression for the area of a square with the given perimeter.

1. P= (12x+20y) in.
2. P= (36a-16b) cm.

  • algebra -

    In a square the perimeter would be 4 times the length of a side,
    so divide 12x + 20y by 4 to get 3x+5y as the length of the side
    Then the area of the first one would be
    (3x+5y)(3x+5y) or (3x+5y)^2

    do the second one the same way
