How do you sketch and label a trapezoid that has an area of 100cm?

To sketch a trapezoid with an area of 100 cm², start by drawing two parallel lines for the top and bottom bases. Label the lengths of the bases as ( b_1 ) and ( b_2 ), and the height as ( h ). Use the formula for the area of a trapezoid, ( \text{Area} = \frac{1}{2} (b_1 + b_2) h ), to determine appropriate dimensions that satisfy the area requirement. For example, you could set ( b_1 = 10 ) cm, ( b_2 = 20 ) cm, and calculate ( h ) as 5 cm.
