Mathematics
1 answer:
prohojiy [21]3 years ago
3 0

Answer: 300x200

Step-by-step explanation: First of all...Your perimeter equals 2x+3y. X=length, y=width.

2x+3y=1200

3y=1200-2x

y=400-(2/3)x

y=400-(2/3)x

Your Area = xy=x(400-2x/3)=400x-2^2/3

dA/dx=400-4x/3=0

4x/3=400

4x=1200

x=300ft length

y=400-(2/3)(300)=200ft

I hope this helps you!
