Question

The area of a hall is given by (x²+2x-35)Sq.units.Find the length and breadth of the hall. a) - l=(x+7) B=(x-5) b) - l=(x-5) B=(x+7) c) - l=(x+5) B=(x+7) d) - l=(x-5) B=(x-7)​

Answer 1

Answer:

length = (x+7)

breadth=(x-5)

Step-by-step explanation:

area of the hall is

$( {x}^{2} + 2x - 35)$

by middle term splitting

$( {x}^{2} + 2x - 35) \\ \\ {x}^{2} + 7x - 5x - 35 \\ \\ x(x + 7) - 5(x + 7) \\ \\ (x - 5)(x + 7)$

length = (x+7)

breadth=(x-5)
