What is the height of the equilateral triangle whose side is 10 cm?

a=√75=√3√25=5√3.

How do you find the area of an equilateral triangle?

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 the area of equilateral triangle of side 10 cm each * 2 points?

253 ​cm2.

How do you find the side of an equilateral triangle with Class 10?

Formulas and Calculations for an Equilateral Triangle: Area of Equilateral Triangle Formula: K = (1/4) * √3 * a. The altitude of Equilateral Triangle Formula: h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60 degrees. Sides of Equilateral Triangle: a equals b equals c.

How do you find the side length of an equilateral triangle?

Since the equilateral triangle shares a side with the square, each of the five sides that are outlined have the same length. Recall that the height of an equilateral triangle splits the triangle into congruent triangles. We can then use the height to find the length of the side of the triangle.

What is the area of one side of an equilateral triangle?

One side of an equilateral triangle is 6 cm. Its area by using Heron’s formula is One side of an equilateral triangle is 6 cm. Its area by using Heron’s formula is

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.

What is the length of an equilateral triangle?

An equilateral triangle has equal sides of length 20 cm, and the angles between them are 45 degrees. What is the area of the triangle? GIVEN: an ISOSCELES triangle, having 2 of its equal sides 20 cm each, with 45° angle between them.

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”.
