The area of a triangle is (1/2) x base x height. The height is perpendicular to the base. In this case, you can take the 10 cm as the base, and calculate the height with Pythagoras' formula. If you split the base in half now you have two 5-12-13 right triangles, so the height is 12 cm and the area is (1/2)*(10cm)*(12cm) = 60 cm2

What is the Surface area of isosceles triangle?
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
What is the area of an isosceles right triangle whose hypotenuse is 12 2?
The length of the hypotenuse, alone, is not sufficient to determine the area of a triangle.
What is the surface area of an isosceles triangle?
i is usually 1/3 of the area but if you want to find the area off a certain
If the sides of a triangle are doubled then the area becomes?
If the sides of a triangle are doubled then the area becomes quadrupled (four times as large).
What is the area of an isosceles triangle that has a base of 5 cm and a height of 7cm?
17.5cm squared
