Answer 2

Answer:

Step-by-step explanation:

we know that area of the square is = side x side

side2=169

side=√169

(13 x 13 = 169)

so,

each side is = 13 units

let's take another example:

A square board has an area of 121 square units. How long is each side of the board?

area of the square is = side x side

side2=121

side=√121

(11 x 11 = 121)

so,

each side is 11 units
