To find the height of an equilateral triangle, we can use the formula:
Height = (√3/2) * side length.
Given that the side length is 8 meters, we substitute that into the formula:
Height = (√3/2) * 8.
Using the approximate value provided for the square root of 3 as 7/4, we rewrite the formula:
Height = (7/4 * 8) / 2.
Simplifying:
Height = (7 * 8) / 8.
Height = 7.
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 7 meters.
The height of an equilateral triangle equals 3√2
times the side length. Using 7/4
for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?
