List the formula for the area of a trapezoid and then find the area of the trapezoid shown below.

Question

Below is the image for the question.
Base: 11cm
Height: 4cm
Area: 3cm

Answer 1

Formula for the area of a trapezoid:
Area = (1/2) * (a + b) * h

Plugging in the given values:
Area = (1/2) * (11 + 3) * 4
Area = (1/2) * 14 * 4
Area = 7 * 4
Area = 28 cm²

Therefore, the area of the trapezoid shown in the image is 28 cm².
