Use the image to answer the question.

An illustration shows a trapezoid with parallel sides on the top and bottom. The top side is 24 centimeters and bottom side is 20 centimeters. Two perpendicular dotted lines of 10 centimeters are drawn from the bottom vertices to the top side. The two perpendicular lines are denoted by 4 right angle symbols.

What is the area of the quadrilateral?

To find the area of a trapezoid, we can use the formula:

\[ \text{Area} = \frac{(b_1 + b_2)}{2} \times h \]

where \( b_1 \) and \( b_2 \) are the lengths of the parallel sides, and \( h \) is the height.

In this case:

  • \( b_1 = 24 \) cm (the top side)
  • \( b_2 = 20 \) cm (the bottom side)
  • \( h = 10 \) cm (the height, as given by the length of the perpendicular lines)

Now, plug these values into the formula:

\[ \text{Area} = \frac{(24 + 20)}{2} \times 10 \] \[ = \frac{44}{2} \times 10 \] \[ = 22 \times 10 \] \[ = 220 , \text{cm}^2 \]

Therefore, the area of the trapezoid is 220 cm².

So the correct response is:

220 cm²
