Answer 2

Answer :

›»› The perimeter of a rectangle is 12x² - 6x² - 4xy.

Step-by-step explanation :

Given :

• Length of a rectangle = 5x² - 3y².
• Breadth of a rectangle = x² - 2xy.

To Find :

• The perimeter of rectangle = ?

Formula required :

Formula to calculate the perimeter of a rectangle is given by,

→ Perimeter of rectangle = 2(l + b).

Here,

• l is the Length of a rectangle.
• b is the Breadth of a rectangle.

Or we can say that l and b are the two adjacent sides of a rectangle.

Solution :

We know that, if we are given with the length of a rectangle and breadth of a rectangle then we have the required formula, that is,

→ Perimeter of rectangle = 2(l + b).

By using the formula to calculate the perimeter of a rectangle and substituting the given values in the formula, we get :

→ Perimeter of rectangle = 2{(5x² - 3y²) + (x² - 2xy)}

→ Perimeter of rectangle = 2(5x² - 3y² + x² - 2xy)

→ Perimeter of rectangle = 2(5x² + x² - 3y² - 2xy)

→ Perimeter of rectangle = 2(6x² - 3y² - 2xy)

→ Perimeter of rectangle = 2(6x²) - 2(3y²) - 2(2xy)

→ Perimeter of rectangle = 12x² - 2(3y²) - 2(2xy)

→ Perimeter of rectangle = 12x² - 6x² - 2(2xy)

→ Perimeter of rectangle = 12x² - 6x² - 4xy.

Hence, the perimeter of a rectangle is 12x² - 6x² - 4xy.
