Question

The sides of a triangle are 2x, 3x–5y and 4x+2y–1, find its perimeter​

Answer 1

Step-by-step explanation:

perimeter=sum of all sides.

2x+3x-5y+4x+2y-1. 1

9x-3y-1=. 2

X=1+3y

put vale of x in 1

2(1+3y) +

Answer 2

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
