It depends on the size of the triangle.
It is half the base times height.
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
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
An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.

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.
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.
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
An isosceles triangle is a triangle that has two equal sides.
