ANSWER:
square root of ( 100x^2 + 60x + 9 )
An expression to represent the length of each side of the rug is:
square root of ( 100x^2 + 60x + 9 )
STEP-BY-STEP EXPLANATION:
Let's establish that the area of a square is the length of one of its sides squared.
Area of square = Side^2
THEREFORE:
To find the length of each side of the square, we will make side the subject in the formula as displayed below.
Area of square = Side^2
Side^2 = Area of square
Side = square root of ( area of square )
From this, we will substitute the given expression for the area of the square rug to obtain the expression for the length of each side of the rug.
Side = square root of ( 100x^2 + 60x + 9 )
