Question

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)
