Question

give possible expression for the length and breadth of the triangle which has area a^2+6a+8

Answer 1

Heya !!





Area = a²+6a + 8




=> a² + 2a + 4a + 8



=> a ( a + 2 ) + 4 ( a + 2 )



=> ( a + 2 ) ( a + 4 )




-----------------------------------------





Area of rectangle = L × B


a² + 6a + 8 = ( a + 2 ) ( a + 4 )




Hence,



Length = a+ 4 and Breadth = a +2

Answer 2

the above shows the expression for l &b
