Write the expression as a polynomial in standard form.Perimeter = Part BCreate an expression that represents the area of the rectangle above. Write the expression as a polynomial in standard form. Area =

Answer 1

Answer:

Perimeter = 6x + 8

Area = 2x² + 5x + 3

Step-by-step explanation:

The length of the rectangle = x + 1

The width of the rectangle = 2x + 3

Perimeter = 2(Length + Width)

Perimeter = 2(x + 1 + 2x + 3)

Perimeter = 2(3x + 4)

Perimeter = 6x + 8

Area = Length x Width

Area = (x + 1)(2x + 3)

Area = 2x² + 3x + 2x + 3

Area = 2x² + 5x + 3
