Question

the area of square is 220 m square the length of its diagonal

Answer 1

here is your answer

given :

area of a square = 220 m²

to find : length of square's diagonal

solution :

let the side of the square be "a"

area of a square = a²

220 = a²

a = 14.83 meter

length of square's diagonal = a√2

length of square's diagonal = 14.83*√2 = 20.96 meter (approx.)

so, the length of square's diagonal is 20.96 meter.
