We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square an
JulijaS [17]
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 = ( x^{2} +5x)/2 <- equation1
Area of square = Side* Side= x*x = x^{2}  <- equation2

As per given data, Equation1 and equation 2 are equal
so 
( x^{2} +5x)/2 = tex] x^{2} [/tex]  
x^{2} +5x = 2 x^{2}
2 x^{2} -  x^{2}   = 5x
x^{2}  = 5x
x = 5

So the side of square = 5 units  

For Square, both dimensions are equal.
