Step-by-step explanation:

length = (2x + 3) units

width = (x - 7) units

Area = 2( length × width)

Area = 2( (2x + 3) × (x - 7) )

Area = 2( 2x² - 14x + 3x - 21)

Area = 2 ( 2x² -11x - 21)

Area = 4x² - 22x - 42

Answer:

Step-by-step explanation:

x² + 11x + 24

x² + 3x + 8x +24

x ( x + 3 ) + 8 ( x + 3 )

( x + 3 ) ( x + 8 )
