Question

What is the perimeter of a rectangle with a length of (x^2+x) and a width of (2x^2+3x)

Answer 1

Perimeter = 6x² + 8x

Explanation:

Perimeter = 2(length + width)

perimeter = 2((x²+x)+(2x²+3x))

perimeter = 2(x²+2x² + x+3x)

perimeter = 2(3x² + 4x)

perimeter = 2*3x² + 2*4x

perimeter = 6x² + 8x
