## How do you find the area of a equilateral triangle with height?

In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.

## What is altitude of a triangle for Class 10?

The altitude or height of an equilateral triangle is the line segment from a vertex that is perpendicular to the opposite side. It is interesting to note that the altitude of an equilateral triangle bisects its base and the opposite angle.

**What is the area of an equilateral triangle with sides of 10 inches and height of 7?**

35 square inches

Summary: The area of an equilateral triangle with sides of 10 inches and height of 7 inches is 35 square inches.

**What is equilateral triangle class 9?**

In geometry, an equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.

### What is the height of an equilateral triangle?

The height of an equilateral triangle is 10 cm . Its area is The height of an equilateral triangle is 10cm. Its area is Was this answer helpful?

### How do you find the area of an equilateral triangle?

Solution: If the side (or the base) of the equilateral triangle= 10 cm, the altitude on the base = 10 sin 60. And so the area of the equilateral triangle = [10×10 sin 60]/2

**How do you find the semiperimeter of an equilateral triangle?**

Semiperimeter of Equilateral Triangle: s = 3a / 2. Area of Equilateral Triangle: K = (1/4) * √3 * a 2. Altitude of Equilateral Triangle h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60°. Sides of Equilateral Triangle: a = b = c. 1. Given the side find the perimeter, semiperimeter, area and altitude.

**How do you find all the unknown values of an equilateral triangle?**

For equilateral triangles h = ha = hb = hc. If you have any 1 known you can find the other 4 unknowns. So if you know the length of a side = a, or the perimeter = P, or the semiperimeter = s, or the area = K, or the altitude = h, you can calculate the other values.
