Question

can someone say the answer please​

Answer 1

Answer:

Step-by-step explanation:

Let a and b be two adjacent sides of rectangle.

Then we know perimeter of rectangle will be 2(a+b).

Here two adjacent sides are 2$x^{2}$-5xy+3z²and 4xy-x²-z².

thus perimetre =2(a+b)=2(2x² - 5xy + 3z²+4xy - x² -z²).

=2(x² + 2z² -xy).

=2x² +4z²-2xy
