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)
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)
