The area of a triangle cannot be determined by its length and withgt or width, even. You need the length and the perpendicular height.
third leg 5, area 30
30 sq cm ((12 x 5)/2)
Triangles do not have a "length", so I am going to assume you mean the height is 5. The area would then be 30. 1/2 base x height = Area 1/2 (12) x 5 = 30
The hypotenuse is 30.
The length of two sides is not enough to define a triangle. It can have any area between 0 and 300 square feet.
30
third leg 5, area 30
1/2 length multiplied by height.
Same as you would find the area of any triangle A = (1/2)[base][height]
To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.
30 sq cm ((12 x 5)/2)
The area of any triangle, including this one is(1/2 the length of the base) multiplied by (the height).Now you know how to find the area of any triangle that may come your way.
Triangles do not have a "length", so I am going to assume you mean the height is 5. The area would then be 30. 1/2 base x height = Area 1/2 (12) x 5 = 30
30
It is: 0.5*12*5 = 30 square feet
If the shortest leg of a 30-60-90 triangle has length 12, the length of the hypotenuse is: 24
The hypotenuse is 30.
