Answer 1

Answer:

P=8x²+12y

Step-by-step explanation:

P=2L+2W; L=4x²-x+2y; W=x+4y; P=2(4x²-x+2y)+2(x+4y);

P=8x²-2x+2x+4y+8y; P=8x²+12y

Answer 2

Answer:

• P = 8x² + 12y units

Step-by-step explanation:

Given sides of rectangle:

• x + 4y
• 4x² - x + 2y

Its perimeter is:

• P = 2(l + w)
• P = 2(x + 4y + 4x² - x + 2y)
• P = 2(4x² + 6y)
• P = 8x² + 12y
