Question

if the area of rectangular plot is 35y²+13y-12 . find the length and breadth

Answer 1

hiii!!!

here's ur answer...

given the area of the plot = 35y² + 13y - 12

= 35y² + ( 28y - 15y ) - 12

= 35y² + 28y - 15y - 12

= 7y ( 5y + 4 ) - 3 ( 5y + 4 )

= ( 5y + 4 ) ( 7y - 3 )

length = ( 5y + 4 ) and breadth = ( 7y - 3 )

hope this helps..!!

Answer 2

Hey mate!

Answer:

__________________________________________________

Given,

Area of the rectangular plot

= 35y² + 13y - 12

Length = ?

Breadth = ?

Now, factorising the given equation, we get

=> 35y² - 15y + 28y - 12

=> 5y(7y - 3) + 4(7y - 3)

=> (5y + 4)(7y - 3)

Therefore,

Length of the rectangular plot = (5y + 4)

Breadth of the rectangular plot = (7y-3)
