Question

the length and the breadth of a rectangular Park are in the ratio 4 is to 3 the cost of fencing the park at 15.25 per metre is 2135 find the perimeter of the park and also find the length of its side

Answer 1

Answer:

Step-by-step explanation:

perimeter= total cost/ cost per m

2135/15.25=  140

perimeter = 2(l+b)

let ratio = x

2(4x+3x) = 140

7x = 140

x= 20m

length = 4x = 80m

breadth = 3x = 60m
