Question

the length of a rectangle 6x+5y and its breadth 4x-3y.what is the perimeter of the triangle?​

Answer 1

Answer:

Perimeter of rectangle is $4(5x+y)$

Step-by-step explanation:

Given : Length of rectangle = $(6x+5y)$

          Breadth of rectangle = $(4x-3y)$

To find : Perimeter of rectangle

Solution :

• We know the formula,
• Perimeter of rectangle = $2(length + breadth)$

                                = $2[(6x+5y)+(4x-3y)]$

                                = $2(6x+5y+4x-3y)$

                                = $2(10x+2y)$

                                = $4(5x+y)$

• ∴ Perimeter of a rectangle is $4(5x+y)$

Answer 2

Given,

The length of a rectangle $6x+5y$ and breadth of a rectangle $4x-3y$

We have to find the perimeter of a rectangle

Formula,

Perimeter of a rectangle $= 2(l+b)$

Here, $l=6x+5y$ and $b=4x-3y$

Substitute the values, we get

$= 2(6x+5y+4x-3y)$

$=2(10x+2y)$

$=20x+4y$

Therefore, the perimeter of a rectangle is $20x+4y$.
