Question

A rectangle has a length of 6x^3 y^2 - 1 and a width of 3xy + 2. The formula for the perimeter of a rectangle is P=2l + 2w, where l is the length and w is the width. What is the perimeter of the rectangle? Simplify your answer.

Answer 1

P = 2 l + 2 w

P = 2 ( l + w )


P = 2 ( 6 x ^ 3 y ^ 2 - 1 + 3 x y + 2 )

P = 2 ( 6 x ^ 3 y ^ 2 + 3 x y + 1 )

Answer 2

OR

P = 2 ( 6 x ^ 3 y ^ 2 + 3 x y + 1 )

P = 12 x ^ 3 y ^ 2 + 6 x y + 2

P = x y ( 12 x ^ 2 y + 6 ) + 2

Answer 3

OR

P = 6 x y ( 2x ^ 2 y + 1 ) + 2
