☸ Required Answer is ⬇ ⬇⬇ ⬇

1. Sides of rectangle = 3x²-5y² nd 7x²-xy

Perimeter = 2(l+b)
=2(3x²-5y²+7x²-xy)
=2(10x²-5y²-xy)
=20x²-10y²-2xy


2. Perimeter of triangle = 7p²-8p+9
Given Sides = 2p²-p+1 nd 11p²-3p+5
let the third side be x
A.T.Q

Perimeter of triangle = sum of all three sides

7p²-8p+9 = 2p²-p+1 + 11p²-3p+5 + x

x = 7p²-8p+9 - (13p²-4p+6)

x = -6p²-4p+3
