Question

The length of a rectangle is 8 centimetres more than its width.ifthe perimeter of the rectangle is 44 centimetre find the length and breadth of the rectangle

Answer 1

l is length 
b is breadth                                    given that l=b+8
perimeter=2 x{l+b}=44
       =2 x [b+b+8]=44  substituting for l
       =2b +8 =22 cancelling 2
        =2b=14
 b=7
l=15
