Question

If perimeter of a rectangle is 10x+4y−8 and its breadth is 2x+y, find its length?

Answer 1

Step-by-step explanation:

1. 2( l+b)=p

2. substitute the values:

        2( l+2x+y)=10x+4y-8

           2l+4x+2y=10x+4y-8

               2l= 10x-4x+4y-2y-8

3. Therefore, Length= 6x+2y-8 / 2

                           L     =  3x+y-4
