Square and square root

The area of a square field is 31684m. Find the length of each side.

Since you know the area of a square is lengh times width,

you can do ...

length x width = 31684

but since you know that length=width

it is just length squared=31684

so,

length = square root of 31684

at the end length of each side of a square are the the same so, if you know one then you know all of the others,

so,

length of each side in this square is=178 meters

178 m

Step-by-step explanation:

The area of a square is the square of one of its sides, so the square root of the area is the length of one of its sides.

√31684 = 178
