Answer:
The perimeter of an equilateral traingle with height 42cm is 126cm.
Step-by-step explanation:
Given that the height or edge of an equilateral traingle is 42cm. With this information, we are asked to find the perimeter of an equilateral traingle.
The perimeter of equilateral traingle is defined as the three times of the length of edge. Mathematically;
→ Perimeter = 3a
By substituting the given values in the formula, we get the following results:
→ Perimeter = 3(42)
→ Perimeter = 126
Hence, the perimeter of an equilateral traingle with height 42cm is 126cm.
