The area of any triangle is
(1/2) times (length of base) times (height).
We think you can probably handle it from there.
Area of any triangle is: 0.5*base*perpendicular height
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.
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
area of a triangle is half the base times the height .5*22*28=308
For all triangles: area = 1/2 * base * height
Area of any triangle is: 0.5*base*perpendicular height
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.
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
area of a triangle is half the base times the height .5*22*28=308
For all triangles: area = 1/2 * base * height
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
It depends on the size of the triangle.It is half the base times height.
17.5cm squared
For all triangles: area = 1/2 * base * height
The area of a triangle = 1/2*base*height = 1/2*5*7 = 17.5 cm2.The fact that it is an isosceles triangle is irrelevant.
Ok to find the area of an isosceles triangle: Find the height first, to do this use this formula: Height = Square root ( one side square - half the base square) Now that you have the height you can calculate the area by the use of this formula: Area = (1/2)(base)(height) This will give you the surface area of an isosceles triangle. Lets do an example: You have a triangle that has two sides that measure 24 meters and a base of 20 meters. Using the formula above for height you will get a height of 21.8 meters Now use the formula above to find the area and it will give you an area of 218 meters square
The area of ANY triangle is base x height. The height must be measured perpendicular to the base. In the case of an isosceles triangle, if you know only the length of the sides, you can figure out the height by Pythagoras' Theorem.
