A = .5*h*b = 36 m2
h = 2b
substitute for h in the first equation with the second equation:
.5*(2b)*b = 36 m2
b2 = 36 m2
b = 6 m
The base of this triangle would be 18 meters. One half*18 meters*16 meters= 72 square meters, this is the area of a triangle formula.
32.4 cm2 - The formula for calcuating the area of a triangle is:- (base/2) x height
Ok to find the area of an isosceles triangle: Find the height first, to do this use this formula: Height = Square root ( one side square - half the base square) Now that you have the height you can calculate the area by the use of this formula: Area = (1/2)(base)(height) This will give you the surface area of an isosceles triangle. Lets do an example: You have a triangle that has two sides that measure 24 meters and a base of 20 meters. Using the formula above for height you will get a height of 21.8 meters Now use the formula above to find the area and it will give you an area of 218 meters square
A triangle with side a: 3, side b: 20, and side c: 20 meters has an area of 29.92 square meters.
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.
The height of the triangle works out as 9 meters
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
A height of 4.2 meters
The height of the triangle is 6 meters
The base of this triangle would be 18 meters. One half*18 meters*16 meters= 72 square meters, this is the area of a triangle formula.
The area of a triangle is base x height / 2. Height should be perpendicular to base.
There are many possibilities depending on its width which if it was 8 meters then its height would be 15 meters
Area of a triangle = (1/2) x (base) x (height) = (0.5) (45) (86) = 1,935 square meters
32.4 cm2 - The formula for calcuating the area of a triangle is:- (base/2) x height
The answer is in the question it must be 114 square meters
Oh, dude, so you got this triangle with a base of 9 meters and an area of 81 square meters, right? Well, the height of that bad boy is technically 18 meters. Yeah, it's like basic math or whatever. So, there you go, the height is 18 meters, like, no big deal.
