give possible expression for the length and breadth of a rectangle whose area is 4a^2+4a-3
Answer :
We have Area of rectangle = 4a2 + 4a - 3
So,
4a2 + 6a - 2a - 3
2a ( 2a + 3 ) - 1 ( 2a + 3 )
( 2a - 1 ) ( 2a + 3 )
And
We know Area of rectangle = Length Breadth
So,
Possible expression for the length and breadth of a rectangle = ( 2a - 1 ) and ( 2a + 3 ) ( Ans )
We have Area of rectangle = 4a2 + 4a - 3
So,
4a2 + 6a - 2a - 3
2a ( 2a + 3 ) - 1 ( 2a + 3 )
( 2a - 1 ) ( 2a + 3 )
And
We know Area of rectangle = Length Breadth
So,
Possible expression for the length and breadth of a rectangle = ( 2a - 1 ) and ( 2a + 3 ) ( Ans )
