The equation is 5 + x - 4 + x - 5 = 10 + 16 + x - 10 and on solving the value of x is 20
The perimeter of a triangle is calculated by the summation of all the sides of a triangle
It is given that both the triangles have the same perimeter, so summation of all the sides of one triangle is equal to summation of all the sides of another triangle
Therefore the equation can be 5 + x - 4 + x - 5 = 10 + 16 + x - 10
Further solving the equation to calculate the unknown variable x
5 + x - 4 + x - 5 = 10 + 16 + x - 10
2x - 4 = x + 16
2x - x = 16 + 4
x = 20
The ēquation is 5 + x - 4 + x - 5 = 10 + 16 + x - 10 and on solving the value of x is 2
