Answer:

Perimeter =<em>14x+10</em>

<em>Area         =</em>  =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

                                        =<em>14x+10</em>

Angle B + Angle C + Angle D = 180°

37° + 49° + Angle D = 180°

Angle D = 180° - 86° = 94°
