Question

Find the length of the side of a field if area of a square field is 81 sq. m?​

Answer 1

Answer: side of square field is 9 m

Step-by-step explanation:

Answer 2

Given area of the square=81cm^2

We know, area of a square= side^2.

Let the side of the square be 'x'.

Clearly,. side^2=area of the square

→ x^2=81

→x=±√81

→x=±9

Therefore we get x= +9cm or -9cm

Lenght of a square can't be negative therefore length of its side is 9 cm.
