Question

Find the area and perimeter of a rectangle with a length of 3x + 2 and a width of 4x + 3.

Answer 1

Answer:

Perimeter =14x+10

Area         =  =$12x^{2}$+17x+6

Step-by-step explanation:

Area of a rectangle=Length *width

                               =(3x+2)(4x+3)

                               =3x(4x+3)+2(4x+3)

                               =$12x^{2}$+9x+8x+6

                              =$12x^{2}$+17x+6

• Then find x using quadratic equation and substitute the values

Perimeter of a rectangle =2(length +width)

                                        =2(3x+2+4x+3)

                                        =6x+4+8x+6

                                        =14x+10
