What is the area of the rectangular box which is 30x + 7 cm by 3× - 27 cm?

Step-by-step 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!
