well the formula for a triangle is half x base x height so if you multiply 14 by 9 you get 126 and half it you get 63 so the area = 63
Area of the triangle: 0.5*5*14 = 35 square units of measurements
The area of a parallelogram with a base of 9 inches and a height of 10 inches is 90 square inches.
To work out area of tringle you say half base x height. So if your base was 4 & height was 6 you would say half of 4 which is 2 x by height which is 6 which is 12 (6x2)
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).
The formula is: Base times Height divide by two.
Area of the triangle: 0.5*5*14 = 35 square units of measurements
To find the area of any triangle... divide the length of the base by 2... then multiply the result by the height.
area = base x height ÷ 2 ⇒ height = 2 x area ÷ base ⇒ height = 2 x 15 ÷ 3 = 10 inches.
40 inches no. that is not right your area is 60 square inches; watch your units area = base x height height = area / base height = 60/20 = 3 inch
Height = Area/Base = 105/15 = 7 inches
4 inches Area= 1/2(base)(height)
The area of a parallelogram with a base of 9 inches and a height of 10 inches is 90 square inches.
To work out area of tringle you say half base x height. So if your base was 4 & height was 6 you would say half of 4 which is 2 x by height which is 6 which is 12 (6x2)
The area of a parallelogram with a base of 20 inches and a height of 8.5 inches is 170 square inches.
The area of ANY triangle is base x height. The height must be measured perpendicular to the base. In the case of an isosceles triangle, if you know only the length of the sides, you can figure out the height by Pythagoras' Theorem.
Area = Base x Height therefore.... 7in x 4in = 28in =area
