Areas of Quadrilaterals

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus 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 find 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 length and \( h \) is the height.

Front

What is the relationship between the diagonals of a rhombus?

Back

In a rhombus, the diagonals bisect each other at right angles.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated using the formula: \( A = s^2 \), where \( s \) is the length of a side.

Front

How do you calculate 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 bases and \( h \) is the height.

Front

If a rhombus has a perimeter of 68, what is the length of one side?

Back

The length of one side of a rhombus can be found using the formula: \( s = \frac{P}{4} \). For a perimeter of 68, each side is \( 17 \).

Front

What is the area of a rhombus with diagonals of lengths 10 and 12?

Back

Using the formula \( A = \frac{1}{2} \times d_1 \times d_2 \), the area is \( A = \frac{1}{2} \times 10 \times 12 = 60 \).

Front

What is the area of a square with a diagonal length of \( 2\sqrt{2} \)?

Back

The area can be found using the relationship between the diagonal and side: \( A = \frac{d^2}{2} = \frac{(2\sqrt{2})^2}{2} = 4 \).

Front

How do you find the height of a parallelogram if the area and base are known?

Back

Rearranging the area formula \( A = b \times h \) gives: \( h = \frac{A}{b} \).

Front

What is the area of a trapezoid with bases 8 and 12, and height 10?

Back

Using the trapezoid area formula: \( A = \frac{1}{2} \times (8 + 12) \times 10 = 100 \).
