Question

the area of rectangular garden is 375 m2 and the length and breadth are in the ratio of 5:3 . What will be the cost of making a 80 cm broad pathway around on all side of the garden ,if cost of making the pathway is rs50 per square meter? ​

Answer 1

Step-by-step explanation:

length = 5x

breadth = 3x

ratio = 5:3

5x × 2x = 375m2

10x^2 = 375m2

=> 37.5 =>

5x = 5 × 37.5 = 133.5m

3x = 3 × 37.5 = 112.5m
