Question

Wire of length 36 cm is bent to form an equilateral triangle find the altitude of the triangle

Answer 1

Answer:

each side of the triangle =36/3=12

therefore find area and equate it to 1/2*b*h Altitude=12^2-6^2=144-36=/108

Answer 2

Answer:

total length of wire=perimeter of eq.triangl

3 side=36

1 side=12

Altitude =√ (12²-6²)

=√(144 -36)=√108=6√3 cm
