Question

7) A long piece of wire of length 90 cm is bent to form an equilateral triangle. What will be the length of each side of the triangle?​

Answer 1

30cm

Explanation:

Perimeter of an equilateral triangle = 3L

Mathematically we have;

P = 3L

Where P = perimeter of the triangle

L = Length

Therefore;

90 = 3L

Divide both side by 3

L = 30cm

Therefore, the length of each side of the triangle is 30cm.
