If a right triangle has an area of 81 meters an a base of 9 meters its height is: 18 meters.
A height of 4.2 meters
The height of the triangle is 6 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).
The answer is in the question it must be 114 square meters
The area of a triangle is base x height / 2. Height should be perpendicular to base.
The area of triangle is : 90.0
The area of triangle is : 100.0
The height of the triangle works out as 9 meters
A height of 4.2 meters
Area of a triangle = 0.5*base*height. In this case, area = 0.5*3*5 = 7.5 metre2.
The height of the triangle is 6 meters
Assuming that the width of the triangle is the base of the triangle and the the length is height we can calculate area as followed: 1/2 Base x Height = Area of a Triangle (8 meters ÷ 2) x 6 meters = 4 meters x 6 meters = 24 meters².
Area of a triangle = (1/2) x (base) x (height) = (0.5) (45) (86) = 1,935 square meters
Area of a right angle triangle is: 0.5*base*height
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).
32.4 cm2 - The formula for calcuating the area of a triangle is:- (base/2) x height
Area=1/2(base*height) where either side can be the base or the height in a right triangle.
