180, the formula to find areas of triangles is 1/2(bh)
Area=18. Area= Base * height / 2 (12*3)/2
18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).
Area = ½base x height = 18; h = 4b, so b/2 x 4b = 18 ie 4b2 = 36making b2 = 9 and b = 3 inches
Answer: 9 in Area is 1/2 base x height So 18 = 1/2 b x 4 That means the base is 36/4 or 9
Since the formula for the area of a triangle is: A = .5 x h x b just go 63 = .5 x b x 18 then 63 = 9b 7 = b
The area of triangle is : 135.0
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
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.
