Question

Which expression represents the perimeter of the rectangle shown below

Answer 1

D. 2x² + 10x - 2

Explanation:

Perimeter of a rectangle = 2(length + width)

Length = x² + 3x - 2

Width = 2x + 1

Perimeter = 2(x² + 3x - 2 + 2x + 1)

Perimeter = 2(x² + 5x - 1)

Perimeter = 2(x²) + 2(5x) - 2(1)

Perimeter = 2x² + 10x - 2
