A. 7
B. 14
C. 14 root 3
D. (7 root 3) /2

Answer 1

B ) 14

Explanation:

The altitude of an equilateral triangle:

h = s √3 / 2, where s is the length of one side of the triangle.

s √3 /2 = 7 √ 3 / : √3

s / 2 = 7

s = 7 * 2

s = 14 units

Answer 2

The altitude of an equilateral triangle:
h = s √3 / 2, where s is the length of one side of the triangle.
s √3 /2 = 7 √ 3 / : √3
s / 2 = 7
s = 7 * 2
s = 14 units
