Question

the side of square land was measured as 150 m and is in error by 0.05 m . What's the corresponding error in the computed area of the land

Answer 1

Answer:

The EDM equipments which are commonly used in land surveying are mainly electronic or microwave ... In Fig 2.15, let the slope distance AB be S and the corresponding horizontal distance be D. ... (b) To what precision the slope angle be measured.Explanation:

Answer 2

Explanation:

Sol. Area = (side)2

d (Area)

d (Area) d (side) = 2 × side

d (Area) = 2 × side × d (side)

d(Area) = 2 × 150 × 0.05

d(Area) = 15 m2
