Question

City park is a square piece of land with an area of 10,000 square yards.Write and solve an equation to find the perimeter of the park.

Answer 1

The area of an square is given by:

`A=l^2`

Where "A" is the area and "l" is the length of the side of the square. Using this we can find the length of the sides of the park.

`\begin{gathered} 10000=l^2 \\ l=√(10000) \\ l=100 \end{gathered}`

The length of the sides is 100 yards. The perimeter of a square is given by:

`P\text{ = 4}\cdot l`

Where P is the perimeter and l is the length of the sides, since we know the length of each side in this case we can calculate the perimeter.

`P=4\cdot10000=40000`

The perimeter is 40,000 yards.
