Question

24 POINTSSS for anyone who answers The of a square garden is 36x^2 -60+25 find the perimeter if x=3

Answer 1

Answer:

The perimeter is 52

Step-by-step explanation:

The area is 36x^2 -60x+25

We set this equal to 0 to find the length and width

A= 36x^2 -60x+25

We notice that this is a perfect square trinomial

(a^2 -2ab-b^2) = (a-b)^2

let a = 6x  and b=5

A=(6x-5) (6x-5)

The length and width are the same since is it a square  (we know it is a square so they have to be equal)

The perimeter of a square is

P =4s

P =4 (6x-5)

Distribute the 4

  = 24x -20

Let x =3

P = 24(3) -20

  =72 -20

 = 52

The perimeter is 52
