Explanation:
____________________
A = L * w ;
A square is a rectangle that has all equation sides;
so; for a square. (L = w).
or, "A = s² " ; in which "s" in the length of any one side.
______________
Since "A = s² "
And "A = 182 ft² " ;
we need to solve for "s" ;
and then find the perimeter of the square with is: "4*s" .
_______________________
A = s² ; ↔ s² = A ; s² = 182 ft² ;
Take positive square root of each side of the equation; to isolate "s" on one side of the equation ; and to solve for "s" ;
√(s²) = √(182 ft²) ;
to get: s = √182 ft, = 53.9629502529281659 ft.
_________________________________
The perimeter: 4* s = 4√(182 ft) = 4* (13.4907375632320415 ft.) ;
_________________________________________________
= 53.9629502529281659 ft.
__________________________________________________
round to 54 ft.

Hope that helpsssss :DD
Ducks have 1 head. Dogs have 1 head.
Ducks have 2 feet. Dogs have 4 feet.
If x = no. of ducks and g = no. of dogs
x + g = 25
2x + 4g = 80
Let's use substitution to solve.
x + g = 25 ⇒ x = 25 - g
replace x with 25 - g in the other equation and solve for g
2x + 4g = 80
2(25 - g) + 4g = 80
50 - 2g + 4g = 80
50 + 2g = 80
2g = 30
g = 15
Now use g = 15 in an earlier equation to find x.
x + g = 25
x + 15 = 25
x = 10
