Answer:
C.) 1953 square meters.
Step-by-step explanation:
I see the rope length is 125 meters from calculating
2x + b = rope length
and y = area = x * b
I see 2x + b = 125
b = 125 - 2x
y = x*(125 - 2x)
maximize 125 - 4x = 0
x = 125/4 = 31.25 meters
so max area = y = 31..25*(125 - 2*31.25) = 1,953.125 square meters
