Question

A square piece of fabric has an area of (9x2 + 24x + 16) square inches. The length of each side of the fabric is (cx + d) in., where c and d are whole numbers. Find an expression for the perimeter of the piece of fabric. Then find the perimeter when x = 2.

Answer 1

If the area of the square is 9x^+24x+16, then the side length wouldd be the square root of that. That would be 3x+4. The perimeter would be 4 times that so the perimeter is 4(3x+4) = 12x+16

Hope that helped
