Perimeter: 5+10+length of its 3rd side
im pretty sure its base*height squared
The base is one third of the perimeter, half of the base times the height is the area.
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Is indeterminate.
Triangles don't have a diameter. They have a base and a height.

The hypotenuse of a right triangle with a base of 24 inches and height of 10 inches is: 26 inches.
Is indeterminate.
You multiply the base and the height and then you divide the answers of that by 2. :)
Formula: Area of triangle= 1/2 * base * height Therefore 42 (area of triangle) = 1/2 * 6 (base) * height 42 = 3 * height 42/3 = (3 * height)/3 14 = height Therefore, the height of triangle is 14 inches
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
30 square inches. Area of triangle = (base x height) divided by 2.
area of a triangle = .5 * base * height In this case .5 * 9 * 14 = 63 square inches
