Question

If the perimeter of a triangle is given by x y − + 3 6 and two of it sides are given by x − 4 9 and y x − + 12 8 , then find its third side.​

Answer 1

Answer:

It is given that

Sides of a triangle are 2x+3y,x+5y and 7x−2y

We know that

Perimeter = Sum of all three sides of a triangle

Substituting the values

P=2x+3y+x+5y+7x−2y

By further calculation

=2x+x+7x+3y+5y−2y

So we get

=10x+8y−2x

=10x+6y
