The area of a triangle is
(1/2) x (length of the base) x (height of the triangle).
You ought to be able to handle it from this point.
Area = 0.5*base*height = 0.5*18*20 = 180 metres2
Area is 108 units2
The area of triangle is : 18.0
If a right triangle has an area of 81 meters an a base of 9 meters its height is: 18 meters.
Area = (1/2) x base x height , so solve this for height; height = 2 x Area / base height = (2)(81)/(9) = 18
The area of triangle is : 135.0
Area = 0.5*base*height = 0.5*18*20 = 180 metres2
The area is 117 units2
Area is 108 units2
The area of triangle is : 18.0
If a right triangle has an area of 81 meters an a base of 9 meters its height is: 18 meters.
Area of traingle = Base * Height / 2 = 18*12/2 = 108 m2
Area = 0.5*12*18 = 108 square inches
Area=18. Area= Base * height / 2 (12*3)/2
Area = (1/2) x base x height , so solve this for height; height = 2 x Area / base height = (2)(81)/(9) = 18
Base * Height / 2 = Area18*20/2=A360/2=A180=AThe area of the triangle is 180 m2.
Area = 0.5*base*height 18 = 0.5*4*H So H = 9 feet
