Explanation

 Calculating the area of an irregular shape might involve several methods of approximation or computational geometry. 

The best approach will depend on the tools available and the level of precision required for the task.

Explanation

 1 link in a 30-m chain = 20 cm

Used in metric land surveys for precise measurements.

Explanation

 A longer chain leads to underestimation of the actual distance.

Explanation

 Standard Length: 33 feet  ,Number of Links: 16

Length of Each Link: 2.0625 feet (2 feet and 0.75 inches)

Purpose:

Used in the Revenue Department for measuring agricultural and land records.

Explanation

Explanation

• The elevation of the Kirthar Mountains is 2,260 meters (7,410 feet).
• The highest peak in the Kirthar Range is Zardak Peak.
• It stands at 7,430 feet (2,260 meters).
• The Kirthar Range is situated along the border of Balochistan and Sindh provinces.
• The hill station of Gorakh, located in the Kirthar Mountains, is situated off Dadu in Sindh.

Explanation

 In chain surveying, the area is divided into a network of triangles, as triangles provide the simplest and most stable geometric figures for accurate measurements

Explanation

   Surveys that show the natural features of a country are known as topographic surveys
