What is the area and perimeter of a triangle 19cm x 21 cm?
To find the area of a triangle, you need the length of the base and the height. If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.
How can you find the perimeter of isosceles triangle?
The answer depends on what information you have but, basically, you need to add together the lengths of the three sides of the triangle.
What is the perimeter of rectangle 3mx6m on the bottom of a triangle?
The perimeter is the sum of all four sides, so you need to calculate 2 x length + 2 x height. The fact that the rectangle is at the bottom of a triangle is irrelevant - except that in specific diagrams, information may be provided that lets you calculate the length or the width of the triangle.
Perimeter of acute triangle?
There is no rule for the perimeter of an acute triangle. You simply need to add the sides.
How do find area of triangle?
1/2bh b=base h=height To find the are of a triangle,you have to multiply the base times height and divide the answer by 2. To find the area of a triangle you need to multiply all the sides of the triangle and then divide by 2.
How do you find the perimeter of a triangle with perpendicular height?
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
How do you find the perimeter of a triangle when the perimeter is 177?
If you know the perimeter, there is no need to find it again.
What is the area and perimeter of a triangle 19cm x 21 cm?

If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.
How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
If two sides of the triangle is 6 and 5 what is the perimeter of triangle?
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.

Do you have to miltiply to find the area of a triangle?
In order to find the area of a triangle, you need to multiply the base of the triangle with the height of the triangle and then halve your final answer.The formula is (Base x Height) / 2Using that, the area of a triangle can be found.Hope that helps.Jamz159

How do you find the area of a triangle without the base?
You need to measure how wide it is and the height of the triangle then multiply them together and the you get your answere.
Why do you need the height to find the area of a triangle?
Because the formula to calculate the area is height x (base/2)
