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.
Find the area for a right triangle with legs measuring 5 and 12 and a hypotenuse measuring 13?
You haven't given the units (inches or centimeters or what?) Anyway the hypotenuse is irrelevant all you need to find the area of a right angle triangle is the length of the other two sides. The formula is 1/2(W x H) = A. Which means half the width x the height gives you the area. In this case the width is 5 and the height is 12 which multiplied together gives 60 (the area of a rectangle of 5 x 12). You then need to half it to find the area of the right angle triangle and the answer is 30. Now you just need to know the units.
How do you find the area of a triangle when the area is given but the base and height are not?
You don't need to find it. From what your question states the area is already given to you.
How do you find the surface area of a rectagle?
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
Why do you need to multiply the area of a triangle by a half?
Because - if you draw lines at right-angles from the base of a triangle vertically until they reach the highest point, then draw a horizontal line that connects those points, touching the highest point of the triangle - the area outside the triangle (but inside the resulting quadrilateral) is exactly half the area of the quadrilateral.
Why do we need to divide the area of a triangle by 2?
Because in effect a triangle is half of a 4 sided quadrilateral
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 height of a triangle?
If you know the area, divide by the half the base. A = 1/2 b x hYou need to know at least one of its acute angles and then use trigonometry to find its height.The answer depends on what information about the triangle you do have.

How do you find the area of an icosahedron?
You would need to divide it into triangles, find the area of each triangle and sum these areas together.
How is the area of a triangle and parallelogram different?
They need not be. A bigger triangle can have the same area as a small parallelogram.They need not be. A bigger triangle can have the same area as a small parallelogram.They need not be.

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)
