It would be 7x7 + 2x2 = 53
2.5*6.4=16, 2.5*4.8=12. 12+12+16+16=56
Answer:
It is a solution.
Step-by-step explanation:
Plug in (-1,2) to both equations:
Plug in -1 to see if 2 comes out:
f(x)=x^2+3x+4
y=(-1)^2+3(-1)+4
y=1-3+4
y=-2+4
y=2
(yes it works)
g(x)=2x+4
y=2(-1)+4
y=-2+4
y=2
(yes it works)
The answer is 150yds if you are adding the perimeter of the square and the dividing fence.
