Answer: 16⅔ yds by 25 yds
Step-by-step explanation:
Let x be the length of 3 fence sections
Let y be the length of 2 fence sections
A = xy
3x + 2y = 100
y = 50 - 1.5x
A = x(50 - 1.5x) = 50x - 1.5x²
dA/dx = 50 - 3x
0 = 50 - 3x
3x = 50
x = 50/3 = 16⅔ yds
y = 50 - 1.5(16⅔) = 25 yds
You take the length of the side and divide it by 2.

Step-by-step explanation:
Answer:
Let the length of shorter piece be x ft.
so '' '' '' '' '' '' = 2 x + 3
A/Q, x + 2 x + 3 = 27
3 x = 24
x = 8
Length of shorter piece = x = 8 ft.
'' '' longer '' = 2 x + 3 = 16 +3 = 19 ft.
Step-by-step explanation:
let x and y be the length of the longer and the shorter pieces of the hose respectively.
By question,
x + y = 27 --- (1)
and,
x - 2y = 3 --- (2)
subtracting (1) by (2), we get,
y-(-2y) = 27-3
=> 3y = 24
=> y = 24/3
=> y = 8
putting y = 8 in (1)
x + 8 = 27
=> x = 27-8
=> x = 19
Therefore, the length of the shorter piece is 8 ft and the length of the longer piece is 19 ft
