Answer 1

Area of square field=1024 m²
1) length of each side=l
l²=1024
l=32m
2) Perimeter=4*side
Perimeter=4*32
Perimeter=128m
3) Speed=4.5km/h=4500m/h
Distance=128*5=640m
Time taken=Distance/Speed
Time taken =640/4500=0.142 hrs.

Answer 2

1) the length of the square is = 32 .
2)perimeter = 32*4=128
3)time taken=592 seconds
