Find the area of a trapezoid where the lengths of the bases are 6 cm and 10 cm respectively, and the height is 4 cm.

Step 1 ：The formula for the area of a trapezoid is \(\frac{1}{2}(a+b)h\), where \(a\) and \(b\) are the lengths of the bases and \(h\) is the height.

Step 2 ：Substitute the given values into the formula: \(\frac{1}{2}(6 cm + 10 cm) \times 4 cm\)

Step 3 ：Simplify inside the parentheses: \(\frac{1}{2}(16 cm) \times 4 cm\)

Step 4 ：Multiply: \(8 cm \times 4 cm\)
