Question

The area ol a rectangle is x^2+9x+18 . if its breadth is
(X+6), find its length.
​

Answer 1

Answer:

Hope my answer helps you mate :-)

Step-by-step explanation:

Let length of rectangle be l

So according to the question

l×(X+6)=x²+9x+18

l=x²+9x+18/x+6

l=x+3. (by long divison method)

Answer 2

Answer:

The length is (x + 3)

Step-by-step explanation:

Given: The area of rectangle = x^2+9 x+18

           and breadth = (x + 6)

           let length be 'l'

So, area of rectangle = length x breadth

x^2+9 x+18 = (x + 6) x l

so, l = (x^2+9 x+18)/(x+6)

         

         _x_+_3__________        <== long division method

(x+6)  )   x^2+9 x+18

      __(-)x^2(-)+6 x___

                    + 3 x + 18

             ___(-)3 x (-) 18____

                        0

so the length is (x+3)
