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.
To represent the contrapositive of the statement "If it is an equilateral triangle, then it is an isosceles triangle," you would first identify the contrapositive: "If it is not an isosceles triangle, then it is not an equilateral triangle." In a diagram, you could use two overlapping circles to represent the two categories: one for "equilateral triangles" and one for "isosceles triangles." The area outside the isosceles circle would represent "not isosceles triangles," and the area outside the equilateral circle would represent "not equilateral triangles," highlighting the relationship between the two statements.
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

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
