A city park is in the shape of a square. The area of the park is 441 yards2. How many feet long is one side of the park? A) 7 fe
IceJOKER [234]

Answer:

One side of the park is 63 feet.

C is the correct option.

Step-by-step explanation:

We have been given that the shape of the city park is a square and the area if the park is 441 square yards.We have to find the side of the park.

We know that the four sides of a square is equal and the area is given by

A=\text{(side)}^2

On substituting the value of area, we get

441=\text{(side)}^2

Take square root both sides and ignore the negative values of side

\sqrt{441}=\text{side}

On simplifying, we get

Side = 21 yards

Now, we know that

1 yard = 3 feet

Hence, we have

21 yards = 3×21 = 63 feet

Therefore, one side of the park is 63 feet.

C is the correct option.
