The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
No because the sum of the 2 smallest sides of a triangle must be greater than its longest side.
This is a right angle triangle.
It is an equilateral triangle that has 3 equal sides of 14 cm
yes
None because the given dimensions will not form any kind of a triangle.

The area of a triangle is calculated using the formula A = 0.5 * base * height. Plugging in the given values, we get A = 0.5 * 14 cm * 6 cm = 42 square cm. Therefore, the area of the triangle is 42 square cm.
There is no triangle with sides 14 cm, 3cm and 8cm. For a triangle to exist the sum of the two shorter sides must be longer than the remaining side. 3 cm + 8 cm = 11 cm < 14cm
Yes it is
Yes.
Yes. The triangle with sides 7 cm, 8 cm, 13 cm is obtuse (the angle opposite the side of 13 cm is 120o) and scalene as none of the sides are equal.
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
The area of every triangle is 1/2 of the product of (length of its base times its height).You can probably take it from there.
The largest angle of the triangle will be opposite its largest side and by using the Cosine Rule it works out as 106.23 degrees.
