Answer:

perimeter = 26

Step-by-step explanation:

perimeter of a rectangle = 2L + 2W

where:

L = 5x² - 2

W = 7 + 3x

Let x = 1

find:  Perimeter

-----------------------------------------------

substitute values into the formula:

P = 2(5 * 1² - 2) + 2(7 + 3 * 1)

P = 2(3) + 2(10)

P = 6 + 20

P = 26

therefore,

the perimeter = 26
