Answer:
Step-by-step explanation:
f(x) = –(x – 3)2 + 9
= 3² - (x – 3)2 identity a²-b² = (a+b)(a - b) where : a =3 and b = x-3
= ( 3+x-3) (3-x+3)
f(x) = x( 6-x)
the perimeter is ; 2(x +6-x) =12
the maximum area of the rectangle is : f(3) = 9 m²

Answer:
50x105m
Step-by-step explanation:
310 (length of field) - 65-65= 200/4=50
Start with the perimeter subtract 65 twice because the length is on two sides. Now the length and width will be equal so divide by 4. Add 65 back because you subtracted it earlier.
