(c) x + 1
(d) x + 2​

Answer 1

Answer:

Hi, here is your explanation.

Mark as brainliest, if this helps.

Step-by-step explanation:

Let the breadth of room is x meter

Then length of room = x+2 (given)

Then area of room = (x+2)x sq meter

If length and breadth increased 1 meter

Then length = (x+2)+1=x+3 meter and breadth =x+1 meter

Then area of new room =(x+3)(x+1) Sq m

As per given in question

(x+3)(x+1)−(x+2)x=11

⇒x

2

+4x+3−x

2

−2x=11

⇒4x−2x=11−3

⇒2x=8

⇒x=4

So breadth of room = 4

And length of room = 4+2=6

Thank you.
