Question

Three sides of a triangle are xcm, ycm and 2x cm. Find the perimeter of a triangle​

Answer 1

Answer:

perimeter of triangle = xcm + ycm = 2x cm

perimeter of one side = 2x cm

= 2xcm X 2xcm

4xcm

Answer 2

Answer:

3xcm + ycm

Step-by-step explanation:

Three sides of a triangle = xcm, ycm and 2x cm

We know that perimeter of a triangle = sum of all the sides

So, perimeter of this triangle = xcm+ycm+2x = 3xcm+ycm
