For the area of a parallelogram, what's the formula?
Correct Answer
B. A= (BH)
Explanation
The formula for finding the area of a parallelogram is A = base x height. In this case, the base is represented by B and the height is represented by H, so the correct formula is A = BH.
2.
There are how many yards in a mile?
Correct Answer
D. 1760
Explanation
There are 1760 yards in a mile.
3.
The area of a Square is...
Correct Answer
A. Side × side
Explanation
The area of a square is calculated by multiplying the length of one side by itself. This is because all sides of a square are equal in length. Therefore, to find the area, we simply multiply the length of one side by itself, resulting in side × side.
4.
3 feet are equal to...
Correct Answer
C. A yard
Explanation
Three feet are equal to a yard. A yard is a unit of length in the imperial system and is equal to three feet. This means that if you have three feet, you can also express it as one yard.
5.
Length × Breadth is...
Correct Answer
A. Area of a rectangle
Explanation
The formula for calculating the area of a rectangle is length multiplied by breadth. Therefore, the correct answer is "Area of a rectangle".
6.
1 gram is equal to...
Correct Answer
B. 1000 milligrams
Explanation
The correct answer is 1000 milligrams because there are 1000 milligrams in 1 gram. This is a standard conversion in the metric system, where milli- represents one thousandth of a unit. Therefore, when converting grams to milligrams, you multiply the number of grams by 1000.
7.
What is the perimeter of a circle?
Correct Answer
C. 2 pi r
Explanation
The perimeter of a circle is the distance around the circle. It is calculated using the formula 2πr, where r is the radius of the circle. This formula represents the circumference of the circle, which is the same as its perimeter. Therefore, the correct answer is 2πr.
8.
What is the perimeter of a square?
Correct Answer
C. 4 x side
Explanation
The perimeter of a square is the sum of all its sides. Since a square has four equal sides, the correct answer is 4 x side, where "side" represents the length of one side of the square.
9.
What is this "A= (BH) / 2" used for?
Correct Answer
A. To know the area of a triangle.
Explanation
The formula A = (BH) / 2 is used to calculate the area of a triangle. This formula represents the product of the base (B) and the height (H) of the triangle divided by 2. By substituting the values of the base and height into the formula, one can easily determine the area of the triangle.
10.
"A = B+H" is the formula...
Correct Answer
D. None of these
Explanation
The formula "A = B+H" does not correspond to any of the given options. It is not used to calculate the area of a triangle, the third angle of a triangle, or the area of a circle. Therefore, the correct answer is "None of these".
