Answer 1

Answer:

Perimeter = (lenght×2) + (width×2)

Perimeter = (2.5n×2) + (2×(4n+5))

Perimeter = 5n + 8n + 10

Perimeter = 13n + 10

The Answer is D

Answer 2

Answer:

13n+10

Step-by-step explanation:

The formula for perimeter of rectangle = 2*(L+B)

L = 4n+5

B = 2.5n

Perimeter = 2 * (4n + 5 + 2.5n)

Perimeter = 2 * (6.5n + 5)

Perimeter = 13n + 10
