Step-by-step explanation:

ar of rectangle = length × breadth

= (4x +1) × ( 2x +15)

= 4x( 2x +15) 1( 2x +15)

= 8x² +60x +2x +15

= 8x²+62x +15 =0

= 8x² +( 60 +2) x +15=0

= 8x² +60x +2x +15 =0

= 4x( 2x+15)+1( 2x +15)=0

= ( 4x +1) ( 2x +15 ) =0

4x +1=0 ; 2x +15 =0

x = -1/4 ; x = -15/2

hopefully helping you.............
