Question

(C) The perimeter of a triangle is (x2y + 10) units. One of the sides is of length (x+y - 4)
units and another side is (3 - 2x2y) units. Find the length of the third side.​

Answer 1

Hey mate Here's ur answer :

Let the third side be x .

Perimeter of a triangle = a+b+c

=>2xy + 10 = x+y-4 + 3-4xy +x

=>2xy+4xy =x+y-1 +x

=>6xy= 2x+y -1

After this I dont know sorry .....______
