Perimeter: 5+10+length of its 3rd side
The base is one third of the perimeter, half of the base times the height is the area.
im pretty sure its base*height squared
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
The area of a triangle can be calculated using the formula: Area = (base × height) / 2. For a triangle with a height of 12 inches and a base of 5 inches, the area would be (5 × 12) / 2 = 30 square inches.
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
4 inches x 3 sides = 12 inches for the perimeter.
