Question

Q.15 The area of a square field is 30 1/4
m square. Calculate the length of the side of square.​

Answer 1

Answer:

area of square= side sq.

Step-by-step explanation:

121/4= side sq.

sq.root both = side

11/2 = side

answer is 11/2 m

Answer 2

We are given the area of a square field

$area = 30 \times 1 \div 4 \: {m}^{2} \\ =(( 30 \times 4) + 1) \div 4 \\ = 121 \div 4 \: {m}^{2}$

Let the length of the side of the square be

$x$

Area of the square will be

${x}^{2}$

We know the value of area of the square.

${x}^{2} = 121 \div 4 \\ x = \sqrt{121 \div 4} \\ x = 11 \div 2$

Therefore length of the side of the square is

$11 \div 2 \: m$
