27.111 square units.
This is an isosceles triangle with legs 8 & 8 and base 14. It can be split into two right triangles with base 7, and hypotenuse 8, so the other leg (which will be the height) is √(8² - 7²) = √15.
So the area of the original triangle is (1/2)*base*height = (1/2)*(14)*(√15) = 7√15 = 27.111
The free app Universal Triangle Solver [see related link] calculates the missing information as long as you have 3 pieces of info (3 sides, 2 sides + angle, etc.) It will tell you if there is more than one solution. For a unique solution it gives the area. I typed in the 3 sides (8,8,14) and got the same solution.

What is the length of the sides of an equilateral triangle?
It depends on how big the triangle is. Find out the length of one side and then all the rest of the sides will be the same.
What triangle is the one with only one side a different length?
An isosceles triangle has 2 equal sides and 1 side different in length
Can 9.2 14.5 17.1 be the lengths of the sides of a triangle?
Yes check: the sum of the two length sides > the 3rd length side the difference of the two length sides < the 3rd length side
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
Can an equalateral triangle have only two sides of equal length?
No because then it would be an isosceles triangle. Scalene triangles have no sides of the same length. Isosceles have two sides of the same length and equilateral has all side of an equal length.
What shape has no congruent sides?
If a triangle does not have the same length side as another triangle the sides are not congruent.
What is a triangle with sides of unequal length called?
A scalene triangle (all unequal side length's).
What is the length of the sides of an equilateral triangle?
It depends on how big the triangle is. Find out the length of one side and then all the rest of the sides will be the same.
What is a triangle with no equal sides of length?
A triangle with no equal side lengths is a scalene triangle.
Can some scalene triangle are isosceles triangle?
No, because a scalene triangle is a triangle with no sides the same length. An isosceles triangle is a triangle with two sides the same length and one side different
What is the area of a triangle that is 12 in and 16 in?
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
The perimeter of a triangle with equal sides is 36 miles what is the length of each side?
The length of each side of the triangle is 12 miles.
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
What triangle is the one with only one side a different length?
An isosceles triangle has 2 equal sides and 1 side different in length
Can 9.2 14.5 17.1 be the lengths of the sides of a triangle?
Yes check: the sum of the two length sides > the 3rd length side the difference of the two length sides < the 3rd length side
What are the names of the triangles by side lenghts?
Scalene triangle = All sides are different lengths Isosceles triangle = Two sides have the same length Equilateral triangle = All three sides are the same length
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
