The perimeter of each is the sum of the lengths of its sides.
Triangle Perimeter = 16 + 4x-3 +3x = 7x+13
Square Perimeter = 2x +2x +2x +2x = 8x
If these are equal, you have

The length of a side of the square is 26 units.
10m+27 you add the sides to find perimeter so add 2m+2m+2m and so on and it gives u 10m+27
