Step-by-step explanation:

Given:−

Ratio of Length and breadth = 5:3

owner spent Rs 6000 for surrounding it from all sides at Rs.7.50 per metre.

Tofind:−

difference between its length and breadth

Solution:−

Let the length be 5x and breadth be 3x

Perimeter of rectangle = 6000/7.5

Perimeter of rectangle = 800 m

we know that,

≫ perimeter of rectangle = 2(l+b)

»» 2(5x + 3x) = 800

»» 5x + 3x = 800/2

»» 8x = 400

»» x = 400/8

»» x = 50

★ So, we get the Value of x = 50

≫ Length 5x = 5 × 50 = 250

≫ breadth 3x = 3 × 50 = 150

Difference between length and breadth

⠀⠀⠀= 250- 150

≫ 100

Hence Difference between length and breadth is 100
