Question

A rectangle has an area of x^2 + 7x + 12. Find the length and the width of the rectangle.

Answer 1

Answer: Length= (x+4)

               Breadth= (x+3)

Step-by-step explanation: Area of rectangle= length x breadth

                                        => $x^{2}$+7x+12

                                       => $x^{2}$+3x+4x+12

                                      => x(x+3)+4(x+3)

                                      => (x+4)(x+3)
