Answer :

40 m

Explanation:

given the ratio between the Length and the breadth of the rectangular field is 7 : 4

given the ratio between the Length and the breadth of the rectangular field is 7 : 4let the length and breadth of the rectangular field be 7x and 4x respectively.

given the ratio between the Length and the breadth of the rectangular field is 7 : 4let the length and breadth of the rectangular field be 7x and 4x respectively.ATQ, the cost of fencing the rectangular field @ 75 rupees per m is rupees 16500

therefore perimeter of the rectangular field = 16500/75

therefore perimeter of the rectangular field = 16500/75= 220m

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m➡ 7x + 4x = 220/2

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m➡ 7x + 4x = 220/2➡ 11x = 110m

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m➡ 7x + 4x = 220/2➡ 11x = 110m➡ x = 110/11

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m➡ 7x + 4x = 220/2➡ 11x = 110m➡ x = 110/11➡ x = 10m

therefore perimeter of the rectangular field = 16500/75= 220mformula for the perimeter of a rectangle is 2(l + b)➡ 2(l + b) = 220m➡ 2(7x + 4x) = 220m➡ 7x + 4x = 220/2➡ 11x = 110m➡ x = 110/11➡ x = 10mhence,
