Question

give possible expression for the length and breadth of the following rectangles in which their areas are given=
35y sq + 13y-12

Answer 1

Area of rectangle = 35y² + 13y - 12

35y² + 28y - 15y - 12 = 0

7y ( 5y + 4) - 3 ( 5y + 4) = 0

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

Area of rectangle = LxB

and we have our possible length and breadth as (7y - 3) (5y + 4)

Answer 2

Given Area:

35y²+13y-12

To Find :

Length and Breadth

Solution :

Factorising 35y²+13y-12

[By mid term spilting]

35y²+13y-12

35y²+28y-25y-12

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

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

Length = 7y-3

Breadth = 5y+4
