Front

What is the formula for the area of a kite?

Back

The area of a kite can be calculated using the formula: \( A = \frac{1}{2} \times d_1 \times d_2 \), where \( d_1 \) and \( d_2 \) are the lengths of the diagonals.

Front

How do you calculate the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: \( A = b \times h \), where \( b \) is the base and \( h \) is the height.

Front

What is the area of a rectangle with a length of 10 units and a width of 5 units?

Back

The area is calculated as: \( A = l \times w = 10 \times 5 = 50 \) units².

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: \( A = \frac{1}{2} \times b \times h \), where \( b \) is the base and \( h \) is the height.

Front

Calculate the area of a triangle with a base of 8 units and a height of 5 units.

Back

Using the formula: \( A = \frac{1}{2} \times 8 \times 5 = 20 \) units².

Front

What is the area of a circle with a radius of 7 units?

Back

The area of a circle is calculated using the formula: \( A = \pi r^2 \). For a radius of 7 units, \( A \approx 153.94 \) units².

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is calculated using the formula: \( A = \frac{1}{2} \times (b_1 + b_2) \times h \), where \( b_1 \) and \( b_2 \) are the lengths of the two bases and \( h \) is the height.

Front

Calculate the area of a trapezoid with bases of 10 units and 6 units, and a height of 4 units.

Back

Using the formula: \( A = \frac{1}{2} \times (10 + 6) \times 4 = 32 \) units².

Front

What is the area of a square with a side length of 4 units?

Back

The area of a square is calculated as: \( A = s^2 = 4^2 = 16 \) units².

Front

What is the relationship between the area of a rectangle and the area of a parallelogram with the same base and height?

Back

The area of a rectangle is equal to the area of a parallelogram when both have the same base and height.
