Explanation:

given,

length = 30x + 7

width = 3x - 27

we know,

area = length × width

so, after inserting the values we got,

(30x + 7) (3x - 27)

30x( 3x - 27 ) + 7( 3x - 27)

90x² - 810x + 21x - 189

90x² - 789x - 189

therefore required area of the given rectangle is 90x² - 789x - 189.

hope this answer helps you dear...take care and may u have a great day ahead!
