A triangle with side a: 8, side b: 11, and side c: 15 cm has an area of 42.85 square cm.
The area of triangle is : 40.0
This is a Pythagorean triangle, ie right angled with hypotenuse = 10 feet, so the area is a half of 8 x 6 , ie 24 sqft
If it's a right angle triangle then side ac is 10 units in length.
A triangle with side a: 5, side b: 8, and side c: 11 units has an area of 18.33 square units.This is not a right triangle, so it has to be calculated as two smaller right triangles, or using Heron's Formula since the side lengths are known.Here p= half-perimeter = (5 + 8 +11)/2 =12A = sqrt {p [(p - a) * (p - b) * (p - c)]}A = sqrt [ 12 (7 x 4 x 1)]A = sqrt [12 x 28]A = sqrt 336 = about 18.33
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
A triangle with side a: 8, side b: 8, and side c: 8 yards has an area of 27.71 square yards.

A triangle with side 8 and height 10 cannot be equilateral if the side and height are measured in the same units (inches, cm, miles etc). And if they are not, there is not sufficient information to answer the question.A triangle with side 8 and height 10 cannot be equilateral if the side and height are measured in the same units (inches, cm, miles etc).

Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.
8 meters
If the sides are different lengths it ain't equilateral...
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
24 cm
Using Pythagoras' theorem the height of the equilateral triangle works out as about 7 cm and so with the given dimensions it would appear to be quite difficult to work out the lateral area.
27.713 square inches.
The answer is 32 cm. because the formula for the area of a triangle is 1/2*base*height. Since its an equilateral triangle, it has equal sides. so just substitute it to the given formula. It will be 1/2*8*8 so therefore its 32 :)
