Question

Find the area and the height of an equilateral triangle whose each side measure : 10 meter

Answer 1

Hey friend, Here is your answer-
Area of equilateral triangle = root 3 / 4 × side2
= root 3 /4 × 10^2
= root 3 /4 × 100
= 25 root 3 m2

Hight by using Pythagores theorem,
10^2 = h^2 + (10/2)^2
100 = h^2 + 25
h^2 = 75
h = 5 root 3 m

Hope it will help you.

Answer 2

Answer:

Step-by-step explanation:

The area of the triangle =√3×10×10]m²

4

=[1.73×10×10]m²

[Therefore √3=1.73]

=43.25m²
