Answer:
~669.7(Rounded, original, 669.666666666666...)
Step-by-step explanation:
67/3=22.3
22.3✖️32=713.6
713.6-45=669.7(Rounded)
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2
and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 =

<- equation1
Area of square = Side* Side= x*x =

<- equation2
As per given data, Equation1 and equation 2 are equal
so

= tex] x^{2} [/tex]



x = 5
So the side of square = 5 units
For Square, both dimensions are equal.
Answer:
The side length is 9 m
Step-by-step explanation:
The area of a square is given by
A = s^2
81 = s^2
Take the square root of each side
sqrt(81) = sqrt(s^2)
9 =s
The side length is 9 m
