area of an equilateral triangle is √3a²/4
So, by putting the value of side in this equation , we get :
√3*100²/4 (10 metre=100 cm)
=4330.12cm² is the area of equilateral triangle
as we know that area of triangle=1/2*base*height
so 4330.12=1/2*100*h
50h=4330.12
h=4330.12/50
=86.6024 cm is the height
in metre= 0.86 m
