169 = a ×a = a2Thus, a =√169 = √(13 ×13)13 × 13 = 169 or -13 ×-13 = 169Thus the square root of 169 is +13 or -13.This shows that 169 is a perfect square.

13 and also -13 can be expressed as 13/1 and also -13/1Both numbers have the right to be represented in the type of a reasonable number.Hence, the square root of 169 is a rational number.

The square root of 169 deserve to be calculatedusing different methodssuch together prime administer or the long department method or the repeated subtraction method.

### Square source of 169 by recurring Subtraction Method

Start from 169 and also keep subtracting the successive odd numbers till we obtain zero. The total numbers we subtract is the square root of 169.

169 - 1 = 168168 - 3 = 165165 - 5 = 160160 - 7 = 153153 - 9 = 144144 -11 = 133133 -13 = 120120 -15 = 105105 - 17 =8888 - 19 = 6969 - 21 = 4848 - 23 =2525 - 25 = 0Thus beginning from 169, we have subtracted 13 time to obtain 0. Thus, the square root of 169 is 13.

Write 169. Take it the number in pairs from the right. 69 is preferred as a pair and one stands alone.Now division 1 through a number such the number× numbergives 1 or a number lesser than that.Obtain 1 together the quotient and also 0 together the remainder.Bring down 69for division.Multiply the quotient derived in the previous action with 2. Currently 1× 2 = 2;20 is written in the divisor's place.Find a number which can be included to 20 and this sum deserve to be multiplied by that numbersuch that the product is 69 or lesser 보다 that.We uncover that 3 is the number. 20 + 3 = 23 and also 23 ×3 gives 69.Now our quotient is 13 and also the remainder is 0.

**Example 1:**A new squareplayground is being developed on an area the 676square yards. The ground will certainly be divided into 4 equal sections. What will be the size of every side the thesection?

**Solution:**

The complete area of the park= 676 square yards

Total sections of the park = 4

Area the each section of the park = full area of the park **÷**Number of sections

676 **÷**4 = 169 square yards

We know thateach next of the square = √169

Thus, the length of every side the the section=13yards
