## 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.

## Is an equilateral triangle 180?

The Equilateral Triangle has 3 equal angles. The total sum of the interior angles of a triangle is 180 degrees, therefore, every angle of an equilateral triangle is 60 degrees.

**What is the formula of equilateral triangle height?**

Formula to calculate height of an equilateral triangle is given as: Height of an equilateral triangle, h = (√3/2)a, where a is the side of the equilateral triangle.

**What is the sum of equilateral triangle?**

The sum of all three angles of an equilateral triangle is equal to 180 degrees.

### What angle is equilateral triangle?

60°

Explanation: An equilateral triangle is one in which all three sides are congruent. It also has the property that all three interior angles are equal. In other words, all three angles of an equilateral triangle are always 60°.

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

Formulas and Calculations for a equilateral triangle: Perimeter of Equilateral Triangle: P = 3a 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

**What is the perimeter of an equilateral triangle whose area is 12 cm?**

The perimeter of an equilateral triangle is 3a. Question 1: Find the area of an equilateral triangle whose perimeter is 12 cm. As per formula: Perimeter of the equilateral triangle = 3a, where “a” is the side of the equilateral triangle. Step 1: Find the side of an equilateral triangle using perimeter. Thus, the length of side is 4 cm.

**How do you find the area of a triangle using Pythagoras theorem?**

Take an equilateral triangle of the side “a” units. Then draw a perpendicular bisector to the base of height “h”. Now, apply Pythagoras Theorem in the triangle. Now, put the value of “h” in the area of the triangle equation. Consider an equilateral triangle having sides equal to “a”.

#### How to find the length of side of an equilateral triangle?

Step 1: Find the side of an equilateral triangle using perimeter. 3a = 12 a = 4 Thus, the length of side is 4 cm. Step 2: Find the area of an equilateral triangle using formula.
