Question

if ratio of length and breadth 4:3 of a rectangular horticulter .if the breadth is 40m less than length ,the find perimeter of the horticulture

Answer 1

Let length =4x and breadth =3x

Now , 15.25 is the cost of fencing = 1m

2135 is the cost of fencing = 1/15.25×2135 m

= 140m

Now perimeter is 2(l+b) =140m

2(4x+3x) =140m

14x=140

x=140/14=10 m

Now , length of the side is 4×10= 40m
