Answer:
Step-by-step explanation:
Let length be x and breadth be y .
Along the river no fencing is required so total boundary line of the rectangular land = x + y + y = x + 2y
add divider to it so total length
= x + 2y + y = x + 3y
x + 3y = 2400
area A = xy
y ( 2400 - 3y ) = A
2400y - 3y² = A
For maximum area dA / dy = 0
2400 - 6y = 0
y = 400 yards.
x = 1200 yards
largest area = xy
= 48000 sq yards.

Answer:
17.738
Step-by-step explanation:
to find x we’ll use sine
sin69=x/19
(remember that sine = opposite/hypotenuse)
so x = 19sin69
when typing this in your calculator you might need to change from radian to degree mode
