Question

the length and breadth of rectangular field are in ratio 5:3if cost of fencing around the field is ₹4800 at the rate of ₹50/metre find length and breadth of field?

Answer 1

Hi Friend !!!

Here is ur answer !!!

perimeter of rectangle = 4800/50

= 96

length = 5x

breadth = 3x

2(5x+3x) = 96

8x = 48

x = 6

length = 30

breadth = 18

Hope it helps u :-)

Answer 2

Perimeter of Rectangular field = ₹4800 / ₹ 50 m

Perimeter of Rectangular field = 96 m





Now, let length = 5x and breadth = 3x

Perimeter = 96 m
2( 5x + 3x ) = 96 m
( 5x + 3x ) = 48 m
8x = 48 m
x = 48 / 8 m
x = 6 m




Hence, length = 5x = 5( 6 ) = 30 m
Breadth = 3x = 3( 6 ) = 18 m
