1. To find the area of a triangle, use the formula A = (1/2) * base * height, where A refers to the area, base refers to the length of the base, and height refers to the perpendicular distance from the base to the opposite vertex.
2. To find the area of a triangle, use the formula A = (1/2) * base * height, where A refers to the area, base refers to the length of the base, and height refers to the perpendicular distance from the base to the opposite vertex.
3. To find the area of a triangle, use the formula A = (1/2) * base * height, where A refers to the area, base refers to the length of the base, and height refers to the perpendicular distance from the base to the opposite vertex.
4. Given that the area of a triangle is 110 ft^2 and the base is 10 ft, we can use the formula A = (1/2) * base * height to find the height. Rearranging the formula, we get height = (2 * A) / base. Plugging in the values, height = (2 * 110) / 10 = 22 ft.
5. Given that the area of the parallelogram ABCD is 246 mm^2 and the height is 20.5 mm, we can find the length of the base of triangle ABD using the formula A = (1/2) * base * height. Rearranging the formula, we get base = (2 * A) / height. Plugging in the values, base = (2 * 246) / 20.5 = 24 mm.
To find the area of a triangle, you need to know its base and height. The formula to find the area of a triangle is:
Area = (base * height) / 2
Let's apply this formula to the given questions to find the area of each triangle.
1. Since no base or height is given for the first triangle, we cannot find its area without more information.
2. Similarly, without the measurements of the base or height of the triangle, we cannot calculate its area.
3. Just like the first two questions, if the base or height values are not provided, we cannot determine the area of the triangle without more information.
4. In this question, the area of the triangle is given as 110 ft^2, and the base is given as 10 ft. We can use the formula to find the height of the triangle:
Area = (base * height) / 2
110 = (10 * height) / 2
Multiply both sides of the equation by 2:
220 = 10 * height
Divide both sides of the equation by 10:
22 = height
So the height of the triangle is 22 ft.
5. In this question, the area of the parallelogram ABCD is given as 246 mm^2, and the height is given as 20.5 mm. The triangle ABD is formed by dividing the parallelogram along one of its diagonals.
To find the length of the base of triangle ABD, we can use the formula for the area of a parallelogram, which is the same as that of a rectangle:
Area = base * height
246 = base * 20.5
Divide both sides of the equation by 20.5:
12 = base
So the length of the base of triangle ABD is 12 mm.
