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.............
