1 answer:
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
On substituting the value of area, we get
Take square root both sides and ignore the negative values of 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.

Assuming the shape of the room is a rectangle :
Area = Width x Length.
Let's call width "w" and length "l" . Now if, the width is 4/5 of the length that means 4/5 times length gives us the width, like this :
As given in the question, area of the rectangle is 320 square feet. And as I said before area of a rectangle can be found by multiplying its length and width.
, we can plug w's value in the previous equation to find "l".
Let's plug "l"s value in the equation.
The length is 20 feet and the width is 16 feet.
