A rectangle is twice as long as it is tall. Its height is 5 centimeters. What is its area in square centimeters?
12.5 cm
50 cm
25 cm
30 cm
The length of the rectangle would be twice the height, so it would be 2 x 5 = 10 centimeters.
To find the area of the rectangle, you would multiply the length by the width: 10 cm x 5 cm = 50 square centimeters.
Therefore, the area of the rectangle is 50 cm.
To find the area of the rectangle, we need to know both the height and the length.
Given that the height is 5 centimeters and the length is twice as long, the length would be 2 x 5 = 10 centimeters.
The area of a rectangle is calculated by multiplying the length by the width. Therefore, the area of this rectangle would be 10 cm x 5 cm = 50 square centimeters.
Therefore, the area of the rectangle is 50 square centimeters, not any of the provided options.
pick one from the options
In this case, 50 square centimeters is not one of the provided options. Let's calculate the option that is closest to the correct area:
Given options:
- 65 square yards
- 27.5 square yards
- 18 square yards
- 32.5 square yards
Since the area of the rectangle is 50 square centimeters, we need to convert it to square yards. There are 0.0001 square meters in 1 square centimeter, and 1 square yard is equal to 8361.27 square centimeters.
Therefore, the area of the rectangle in square yards would be approximately 50 / 8361.27 = 0.006 square yards.
Among the provided options, 27.5 square yards seems to be the closest to the calculated value.
Therefore, 27.5 square yards is the best option from the given choices, even though it is an approximation.
Use the formula for the area of a triangle to determine the area of a triangle with base equal to 13 yards and height equal to 5 yards.
65 square yards
27.5 square yards
18 square yards
32.5 square yards
The formula for the area of a triangle is A = 1/2 * base * height.
Given that the base is 13 yards and the height is 5 yards, we can plug these values into the formula:
A = 1/2 * 13 * 5
A = 1/2 * 65
A = 32.5
Therefore, the area of the triangle is 32.5 square yards.
Among the provided options, 32.5 square yards is the correct answer.
Marigold measures the length and height of a triangular sandwich. If the sandwich’s base measures 4 inches and its area measures 7 square inches, what is the height in inches of the sandwich?
3.5 inches
1.75 inches
14 inches
11 inches
The formula for the area of a triangle is A = 1/2 * base * height.
Given that the base of the sandwich measures 4 inches and the area measures 7 square inches, we can plug in these values and solve for the height:
7 = 1/2 * 4 * height
7 = 2 * height
height = 7 / 2
height = 3.5 inches
Therefore, the height of the sandwich is 3.5 inches.
Among the provided options, 3.5 inches is the correct answer.
An illustration shows a triangle with a base of 20 inches and a perpendicular height of 6 inches. The height is a dashed line from the top vertex to the base, splitting the triangle in half, thus forming two triangles. A right angle symbol is shown where the dashed line meets the base, on the right side.
what is the area of the triangle described?
30 square inches
120 square inches
26 square inches
60 square inches
To find the area of a triangle, you can use the formula A = 1/2 * base * height, where base is the length of the base of the triangle and height is the length of the perpendicular height from the base to the vertex opposite the base.
Given that the base of the triangle is 20 inches and the height is 6 inches, you can calculate the area as follows:
A = 1/2 * 20 * 6
A = 10 * 6
A = 60 square inches
Therefore, the area of the triangle described is 60 square inches.
