Question

The length and the breadth of a rectangular field are in the ratio 7:4.The cost of fencing the field at rupees 25 per metre is rupees 3300.Find the dimensions of the field

Answer 1

The length is 84m and breadth is 48m

Answer 2

hello mate here is your answer,

Ratio given = 7:4 (lets consider the values as x)
Cost of fencing = Rs 3300
So cost of fencing per metre = 3300/25= 132 m

So formula to be implemented of rectangles perimetre = 2( L + B ) = 132 m

2( 7x + 4x ) = 132 m
2( 11x ) = 132 m
22x. = 132 m
x => 132/22
x => 6m

Therefore length of rectangle = 7(x) = 7(6) = 42m

breadth of rectangle = 4(x) = 4(6) = 24 m

hope it helps you pls mark as branlist
