Answer
To find the perimeter of the equilateral triangle, we need to add the lengths of all three sides. Since each side is equal in length and measures 6 m, we perform the following calculation:
P=6+6+6=18extm
Thus, the perimeter of the triangle is 18 m.
Step 2
Construct an accurate scale diagram of the equilateral triangle in the space below.

Answer
To draw the scale diagram of the equilateral triangle:
Use a scale where 1 cm represents 1 m.
Measure 6 cm on each side to represent the 6 m length of the triangle.
Draw three equal sides, ensuring that all angles are 60 degrees to form an equilateral triangle.
Label each vertex appropriately.
