What is the perimeter of a 6cm triangle?

Solution: Perimeter of the triangle is the sum of the lengths of its sides. Thus, perimeter = 10 cm. 6.

What is the area of a 6 cm equilateral triangle?

We can use the Pythagorean Theorem or the properties of 30˚−60˚−90˚ triangles to determine that the height of the triangle is √32s . Thus, since s=6 cm , the area is 62√34 cm2 or 9√3 cm2 .

How do you write the perimeter of a triangle?

To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.

How do you find the area of different triangles?

The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h. This formula is applicable to all types of triangles, whether it is a scalene triangle, an isosceles triangle or an equilateral triangle.

How do you find the perimeter of an equilateral triangle?

Question 4. Find the perimeter of an equilateral triangle of side 4.5 cm? Explanation. An equilateral triangle is a triangle having all three sides equal in length. Length of each side of an equilateral triangle = 4.5 cm. Perimeter of an equilateral triangle = ( 3 x Length of each side ) units. = ( 3 x 4.5 ) cm.

What is the length of an equilateral triangle?

An equilateral triangle is a triangle having all three sides equal in length. Length of each side of an equilateral triangle = 4.5 cm Perimeter of an equilateral triangle = (3 x Length of each side) units = (3 x 4.5) cm

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.

How do you calculate the altitude of an equilateral triangle?

Calculator Use. An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. The altitude shown h is hb or, the altitude of b. For equilateral triangles h = ha = hb = hc.
