Question

the 3 sides of triangle are 2p (z-p-y) , 3y (p-y-z) , 4z (z-y-p) find the perimeter of triangle in the simplest form ​

Answer 1

Answer:

add all side length

Step-by-step explanation:

then you get the perimeter

Answer 2

Answer:

Perimeter: Sum of all sides

               = 2p(z-p-y) + 3y(p-y-z) + 4z(z-y-p)

               = 2pz-2p²-2py + 3yp-3y²-3yz + 4z²-4zy-4zp

               = (2pz-4zp)+(-2py+3py)+(-3yz-4yz)-2p²-3y²+4z²

               = -2pz + py - 7yz - 2p² - 3y² + 4z²
