Answer:

Now A△A=l△lb△b=(1202+1005)=0.0667;

△A=0.0667×A

Now A=l.b=120×100=12000m2

⇒△A=0.0667×12000=800.4m2

Area of the field = A±△A=12000±800.4=(1.2±0.08)×104m2

Explanation:

I hope this may help you he

Answer:

35,770 m2

Explanation:

Length = [250+(-5)]m = 245m

Breath= [150+(-4)]m = 146m

Area of rectangular field = l×b

= 245m × 146m = 35,770m2

Hope it's helpful
