You can use trigonometry to find the height of the triangle. Then just use the well-known formula: area = (1/2) times base times height.
You can also use Heron's Formula, which works for any triangle, if you know the three sides.
do 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
Yes. The two equal sides would measure 3.

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
Yes. The two equal sides would measure 3.
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.
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
You can't. It is impossible.
