### Calculating the cost of installing precast compound wall./Cost of the precast compound wall for 1-acre of land.

Let us now calculate the cost of the precast boundary wall for the below-given land area.

Given data:

Length of  side AB = CD = 250 ft.

Length of side AD = BC = 174.24 ft.

Height of precast wall = 5 ft.

Area of rectangular land

= [250 ft. × 174.24 ft.]

= 43,560 sq ft. = 1 acre

[ As 1acre = 43,560 sq ft.]

Perimeter of land

= [side AB + side BC + side CD + side DA]

= [250 ft. + 174.24 ft. + 250 ft. + 174.24 ft.]

848.48 ft.

Length of precast wall

= [perimeter of land - gate opening]

= [ 848.48 ft. - 15 ft.]

= 833.48 ft.

Area of precast compound wall

= [length of the precast wall × height of wall]

= [ 833.48 ft. × 5 ft.]

= 4167.40 sq ft.

The market rate for installing precast RCC compound wall varies from INR 80/-  to 120/- per sq ft.

Let us consider an average rate of INR 100/- per sq ft.

Cost of installing the precast compound wall

= [area of precast wall in sq ft. × rate/sq ft.]

= [ 4167.40 sq ft. × 100/-]

= INR 4,16,740/-
