Question

In an equilateral triangle with its given dimension in cm find the perimeter of the triangle if perimiter=y+4,x+8,4x+y

Answer 1

Answer:

5x+2y+12

Step-by-step explanation:

Please add 3 side

4X+X+Y+Y+4+8=5X+2Y+12

Answer 2

Step-by-step explanation:

equilateral triangle means all sides are equal.

y+4=x+8=4x+y

y-x=4.......（1）

3x+y=8.....（2）

if we add these two equations

4x=12....x=3.,y=7

perimeter =5x+2y+12=15+14+12=29+12=41
