Question

the area of square field is 441 m square and find its perimeter

Answer 1

Area = 441 Square m
Area = length× length
length^2
441= length^2
21^2 = length^2
length = 21 m

Perimeter = 4×21 m
= 84 m

Answer 2

Area of square = side x side = 441

one side = √441 = 21

Perimter of square = 4 x side = 4 x 21 = 84m
