Question

The length and the breadth of the rectangle field are in the ratio 7 ratio 4 the cost of fencing the field at 25 rupees per metre is 3300 find the dimension of the field

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Rupees for fencing 1 sq. m =₹25
Cost of total fencing =₹3300
Area of field =3300÷25
=132 sq. m
Ratio of length and breadth =7 : 4
Let the length be 7x and breadth be 4x
Area of rectangle =length × breadth=132 sq. m
=>7x × 4x = 132
=>28x^2 = 132
=>x^2=132÷28
=>x=√4.71
=>x=2.17
Length=7×2.17=15.19 m
Breadth=4×2.17=8.68m

Hope it helps !!!
