**Exercise 3.6**

**(1) Find the square root of:**

**(2) Find the value of:**

** 5. Find the length of a side a square playground whose area is equal to the area of a rectangular field of dimensions 72 m and 338 m.**

**Solution:**

The area of the playground = 72 x 338 = 24336 m^{2}

The length of one side of a square is equal to the square root of its area. Hence, we just need to find the square root of 24336.

Hence, the length of one side of the playground is 156 meters.
