Answer 1

16x + 4

Explanation:

length of rectangle = 5x + 3

width of rectangle = 3x - 1

Perimeter of rectangle = 2 x width + 2 x length

⇒ perimeter = 2(3x - 1) + 2(5x + 3)

⇒ perimeter = 6x - 2 + 10x + 6

⇒ perimeter = 16x + 4

Answer 2

16x + 4

Explanation:

perimeter of rectangle: 2(Length + Width)

Here the length is 3x - 1 and the width is 5x + 3

using the formula:

2(3x - 1 + 5x + 3)

2(8x + 2)

16x + 4
