Question

A square playground has an area of 169 square yards. There is a fence along one side of the playground. How long is the fence? The fence is yards long.

Answer 1

Answer:

The fence is 13 yards long.

Step-by-step explanation:

Area of square = $Side^2$

Let x be the side of square playground

Area of square playground = $x^2$

A square playground has an area of 169 square yards.

So, $x^2=169$

$x=\sqrt{169}$

$x=13$

There is a fence along one side of the playground.

So, Length of fence along one side = Length of side = 13 yards

Hence The fence is 13 yards long.

Answer 2

Work: Take the square root of 169 (which is 13)<—That equals the length of one side of the fence. The perimeter is 4 times 13 which is 52 yards. Correct Answer: 52 yards
