Question

The area of a rectangle is 5a^2+25a. If its breadth is 25a, then find its length

Answer 1

Solution :

Dimensions of a rectangle :

Breadth ( b ) = 25a

Let length = l

Area = 5a² + 25a [ given ]

=> l × b = 5a ( a + 5 )

=> l × 25a = 5a( a + 5 )

=> l = [ 5a( a + 5 ) ]/( 25a )

=> l = ( a + 5 )/5

Therefore ,

Length ( l ) = ( a + 5 )/5

Answer 2

Answer:

L = (a+5)/5
