                                                                    V = lwh
                                    2x³ + 17x² + 46x + 40 = l(x + 4)(x + 2)
                 2x³ + 12x² + 16x + 5x² + 30x + 40 = l(x + 4)(x + 2)
2x(x²) + 2x(6x) + 2x(8) + 5(x²) + 5(6x) + 5(8) = l(x + 4)(x + 2)
                     2x(x² + 6x + 8) + 5(x² + 6x + 8) = l(x + 4)(x + 2)
                                      (2x + 5)(x² + 6x + 8) = l(x + 2)(x + 4)
                              (2x + 5)(x² + 2x + 4x + 8) = l(x + 4)(x + 2)
                  (2x + 5)(x(x) + x(2) + 4(x) + 4(2)) = l(x + 4)(x + 2)
                          (2x + 5)(x(x + 2) + 4(x + 2)) = l(x + 4)(x + 2)
                                    (2x + 5)(x + 4)(x + 2) = l(x + 4)(x + 2)
                                          (x + 4)(x + 2)           (x + 4)(x + 2)
                                                           2x + 5 = l

_______________________________

<h2>Given:-</h2>

<h3>perimeter of rectangle=26cm</h3>

<h3>Area of rectangle=>30cm²</h3>

<h3>{•°• perimeter of rectangle=2(l+b) }</h3>

<h3>{•°•. Area of rectangle=lxb}</h3>

<h3>So, 2(l+b)=26</h3><h3> =>(l+b)=26/2</h3><h3> =>l+b=13</h3><h3> =>l=(13-b) ----------(1)</h3>

<h3>Again,</h3>

<h3> =>lxb=30</h3><h3> =>(13-b)xb=30 {putting the value of l from equation 1}</h3><h3> </h3><h3> =>13b-b²=30</h3><h3> =>b²-13b+30=0</h3><h3> =>b²-10b-3b +30=0</h3><h3> =>b(b-10)-3(b-10)=0</h3><h3> =>(b-10)(b-3)=0</h3><h3> </h3><h3>or,</h3>

<h3> =>b=10 or b=3</h3>

<h3>putting the value of b in equation (1)</h3>

<h3> =>l=(13-b)</h3><h3> =>l=13-10=3 { taking b=10}</h3><h3> =>l=13-3=10 { taking b=3}</h3>

<h3>Hence, length=3 when breadth=10</h3><h3> length=10 when breadth=3</h3>
