Question

18. A field has measurements of (17.85 + 0.9) m and
(23.52 + 0.6) m. Calculate the area of the field.​

Answer 1

Step-by-step explanation:

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
