Question

Kelvin has a string of length 4.15m. He wants to form equilateral triangles of sides 8 cm using the string . What is the maximum number of such equilateral triangles that he can make with the string .

Answer 1

4.15 meters = 415 centimeters

3(8x) = 415 (3 sides times 8 cm - amount each triangle takes)

24x = 415

x = 17.2917

The maxinum number of triangles he can make is 17.
