∙ 11y agoThe third side must be 18 m. (It cannot be 2.25 m because then the two equal sides would sum to 4.5 m which is less than the third.) Denote the 3 sides by a, b and c and let
s = (a+b+c)/2 = 19.125 m
Then area = sqrt[s*(s-a)*(s-b)*(s-c)]
= 20.21 m2 approx.

∙ 11y agodo you want to know the area in a isosceles triangle or what?
Area of any triangle is: 0.5*base*perpendicular height
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
Area of the right isosceles triangle: 0.5*16*16 = 128 square units
Area = 1/2*base*height = 0.825 sq cm. The fact that the triangle is isosceles is irrelevant: it makes no difference to its area.

What is the length of a leg of an isosceles right triangle if it is area is 72 square inches?
Area of the right isosceles triangle: 0.5*16*16 = 128 square units
V= area of the triangle x length
Area = 1/2*base*height = 0.825 sq cm. The fact that the triangle is isosceles is irrelevant: it makes no difference to its area.
What total do you mean? area? volume? or other mathematical terminologies? or do you mean the total sides of an isosceles triangle? LOL :)) well its angle total will have to be 180 no matter what because each triangle has an interior angle sum of 180. SO yea...................... that is why. :)
Yes providing that it is an equilateral triangle or a a right angle isosceles triangle other wise it's not possible
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
The length of the hypotenuse, alone, is not sufficient to determine the area of a triangle.
For all triangles: area = 1/2 * base * height
