Triangles do not have a "length", so I am going to assume you mean the height is 5. The area would then be 30.
1/2 base x height = Area
1/2 (12) x 5 = 30
The base length is 5.2643 units and the height is 4.55902 units.
Perimeter = 10 + 10 + 12 = 32 units. Area = 48 square units
The area of triangle is : 60.0
A rectangle and a triangle have equal areas. The length of the rectangle is 12 inches, and its width is 8 inches. If the base of the triangle is 32 inches, what is the length, in inches, of the altitude drawn to the base?
The area of triangle is : 12.0
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
12
You haven't told us the question. If you're looking for the area of a triangle, that's 1/2 of (height of the triangle) times (length of the triangle's base).
The base length is 5.2643 units and the height is 4.55902 units.
48in2. To find the area of any triangle - you divide the length of the base by 2, then multiply that figure by the height.
Perimeter = 10 + 10 + 12 = 32 units. Area = 48 square units
The area of triangle is : 60.0
A rectangle and a triangle have equal areas. The length of the rectangle is 12 inches, and its width is 8 inches. If the base of the triangle is 32 inches, what is the length, in inches, of the altitude drawn to the base?
The length of a triangle with a height of 12 inches and an area of 18 square inches is 3 inches, since area is 1/2 * base * height. Therefore, 2 * area divided by height = 2 * 18 /12 = 3
Well, it helps immensely to know the formula for the area of a triangle. The area of a triangle is 1/2 (length of the base) times (height) .Knowing that, all you have to do is draw a triangle in such a way that the length of the base (in cm), multiplied by the height (in cm) is 12 . There are an infinite number of ways to do it, so finding one should not be a problem.
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 area of triangle is : 12.0
