Question

b. The ratio of breadth and length of a rectangular field is 3:5. If the breadth is decreased by 2 m and the length is increased by 3 m, then the ratio changes to 1: 2. Find the area of the original field. in no third of the denominator. The numerator​

Answer 1

Answer:

Given that:

Length of a rectangle field =3x

Breadth of a rectangle field =2x

Area =3456 m  

2

 

3x×2x=3456 m  

2

 

6x  

2

=3456 m  

2

 

x  

2

=576 m  

2

 

x=24 m

Therefore, the length =72 m  

Breadth =48 m

Perimeter of the rectangular field =72+48=120 m

Cost of 1 meter =Rs.4

Cost of 120 meter =Rs.4×120=Rs.480.

This is the required solution.
