This is not an equilateral triangle.
A right triangle has a hypotenuse of 12cm and a leg that is 9cm the other leg would be 7.94. This is a math problem.
Area 51.
To find the area of a triangle, you can use the formula A = 1/2 * base * height. In this case, the base is 18 cm and the height is 9 cm. Plugging these values into the formula, we get A = 1/2 * 18 cm * 9 cm = 81 square cm. Therefore, the area of the triangle is 81 square cm.
Use Pythagoras' theorum a2 = b2 + c2 a2 = (9x9) + (12x12) 225 = 81 + 144 Ö225 = 15cm > 14cm. answer NO.
