Answer:

6.06m

Explanation: equilateral triangle means all the three sides and three angles are same

the sum of interior angle of a triangle is 180 degree

that is the one angle is 180/3 = 60 degree

taking trigonometry

hypoteneous is 7 m

base is 7/2 = 3.5m

sin 60 = perpendicular/ hypotenious

here perpendicular is altitude

value of sin 60 is root3/2

that is root 3/2 = altitude / 7

that is altitude = 7root3/2 = 3.5root3 m = 6.06m
