Question

The length of a room is 6 m longer then its breadth. If the area of the room is 72 m2.calculate breadth-

Answer 1

Hi there,

Given,

Area = 72m^2
Let,the breadth of the room be x

A/q , Length will be x+6

Area= l×b

72=(x+6)×X

72=X^2+6x

x = 6 or -12

-12 is not possible.

hence,breadth = 6 m

Answer 2

Heya ......^_^;
.

Here's ur ans. .⬇
____________________________

Area = 72 m^2

Area of rectangle = l × b

↪ Let the breadth = x

Then , according to the question

Length = x + 6

Area = x ( x+6)

72 = x^2 + 6x

x^2 + 6x - 72 = 0

x^2 + 12x - 6x - 72 = 0

x ( x + 12) - 6 (x + 12 ) = 0

x = -12

x = 6

Since breadth can never be negative

x = 6m

x+ 6 = 12 m

$hence$

Length = 12 m
and
Breadth = 6m
