Well, darling, to find the area of a triangle with those side lengths, you can use Heron's formula. So, plug in those side lengths (a=8, b=11, c=15) into the formula, calculate the semi-perimeter, and then solve for the area. Voilà, you've got yourself the triangle's area.
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
The area of triangle is : 40.0
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

Equilateral triangle means that all sides are equal in length. When it is asked for a height of equilateral triangle it refers to vertical distance from highest point of the triangle to the lowest(Right in the middle). So we got two known and one unknown which tells us that we can use Pythagorean Theorem C2=A2 + B2 A=4 B=? C=8 Solve for B and you will get answer Square root of 48.
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.
