Assuming 2, 8, and 8.5 are the lengths of the sides, the area is 7.929 cm^2.
Using Heron's formula, A = sqrt(s * (s-a) * (s-b) * (s-c))
where a, b, and c are the lengths of the sides and s = (a + b + c)/2
The area of a triangle is 1/2 x base x height. This means that you take half of the side on the bottom of the triangle and multiply it by the height from the base to the tip of the triangle. For example, if the base of the triangle is 4 cm and the height is 2 cm, then the area is: A = 1/2 x b x h A = 1/2 x 4 cm x 2 cm A = 2 cm x 2 cm A = 4 cm2
The area of triangle is : 6.0
What you do is you multiply the base by the height then you must half your answer. Eg: A triangle with a base of 2 cm and a height of 4cm, you would do 2x4=8 then half your answer to get 4cm squared.
A triangle is half of a square so you use the same formula for square (bh or base times height) and divide i by 2 or multiply it by one half. 3*3=9/2=4.5
The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the area of the triangle would be (5 cm x 7 cm) / 2 = 35 cm².
The area of a triangle is 1/2 x base x height. This means that you take half of the side on the bottom of the triangle and multiply it by the height from the base to the tip of the triangle. For example, if the base of the triangle is 4 cm and the height is 2 cm, then the area is: A = 1/2 x b x h A = 1/2 x 4 cm x 2 cm A = 2 cm x 2 cm A = 4 cm2
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 right-angle triangle measures 28cm by 35cm. Such a triangle is half of a rectangle.Therefore 28 x 35 = 980cm2 is the area of a rectangle.980 / 2 = 490cm2 will give the area of the triangle (which is 490cm2).
The area of triangle is : 6.0
That would depend on the dimension of the green triage. If the triangle was formed by joining two opposite corners of the parallelogram then it would be half the area of the parallelogram. Area of parallelogram = 15*2 = 30 square cm. 1/2 the area = 15 square cm.
For a triangle, the area is equal to half the base times the height. A = 1/2*bh where A is the area of the triangle, b is the length of the base, and h is the height. In this case: * A = 1/2 * 5 * 3 = 15/2 cm2 = 7.5 cm2.
The area of a triangle is 1/2 of the base times height. Base x height is 9x8- or 72. Half of 72 is 36. ,
40 Area= half of base times hieght 8x10= 80 80Divided by 2 is 40
What you do is you multiply the base by the height then you must half your answer. Eg: A triangle with a base of 2 cm and a height of 4cm, you would do 2x4=8 then half your answer to get 4cm squared.
Because the area is equal to half the base times height. Suppose you start of with a triangle with base = B cm and height = H cm. Its area = 1/2*B*H cm2. You then double the base to 2B cm and halve the height to H/2 cm and tis gives the new area = 1/2*(2B)*(H/2) = 1/2*B*H cm2, as before.
A triangle is half of a square so you use the same formula for square (bh or base times height) and divide i by 2 or multiply it by one half. 3*3=9/2=4.5
A triangle with side a: 2, side b: 2, and side c: 2 cm has an area of 1.73 square cm.
