6 equilateral triangle bases = 60cm
1 base = 60cm ÷ 6 = 10cm
This tells you each side of a triangle is 10cm since they are all identical and equilateral (all sides same length).
The remaining piece of paper has 2 triangle sides forming the perimeter for each triangle.
2 sides × 6 = 12 sides.
Perimeter of remaining piece of paper
= 12 × 10cm + 60cm + 20cm + 20cm
= 120cm + 100cm
= 220cm
1 base = 60cm ÷ 6 = 10cm
This tells you each side of a triangle is 10cm since they are all identical and equilateral (all sides same length).
The remaining piece of paper has 2 triangle sides forming the perimeter for each triangle.

Perimeter of remaining piece of paper
= 12 × 10cm + 60cm + 20cm + 20cm
= 120cm + 100cm
= 220cm
