What is the length of side \( \overline{AB} \) in a rhombus if \( \overline{AD} = 24cm \)?

Back

The length of side \( \overline{AB} \) is also 24cm in a rhombus.

Front

In rhombus DOGS, if \( DO = 2p + 9 \) and \( OG = 3p - 6 \), how do you find \( GS \)?

Back

Set \( DO = OG \) to find \( p \), then use it to calculate \( GS \). The answer is 39.

Front

What are the properties of a rhombus?

Back

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is given by the formula: \( A = \frac{1}{2} (b_1 + b_2) h \), where \( b_1 \) and \( b_2 \) are the lengths of the parallel sides and \( h \) is the height.
