Question

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

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)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
