Answer:
perimeter = 26
Step-by-step explanation:
<u>perimeter of a rectangle = 2L + 2W</u>
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
