    The expression 16x2 + 40x+25 represents the area of a square rooftop. Write an expression that represents the perimeter of the rooftop?

    Answer:

    4 * √ (16x2 + 40x+25)

    Step-by-step explanation:

    Find the lenght with the inverse formula.

    If A = l²

    l = √A

    then you find the perimeter multipling l * 4

    your expression is:

    4 * √ (16x2 + 40x+25)
