Question

Find the perimeter of a rectangle 6x+y,3x-y

Answer 1

Correct Question:-

Find perimeter of rectangle whose length and breadth are -x+y and 3x-y respectively.

Step-by-step Explanation:-

Given:-

• Length of rectangle=6x+y

• Breadth of rectangle=3x-y

To find:-

• Perimeter of rectangle

Solution:-

We have formula for perimeter of rectangle:

Perimeter of rectangle=2(L+B)

Here:-

L refers to Length

B refers to breadth

Now put value of length and breadth in formula!

⇒ 2(L+B)

⇒ 2[(6x+y)+(3x-y)]

⇒ 2[6x+y+3x-y]

⇒ 2[6x+3x+y-y]

⇒ 2[9x]

⇒ 18x

So the required perimeter of rectangle is 18x.
