Given a trapezoid
24cm base
20cm top
10cm inside

1 answer

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

\[ \text{Area} = \frac{1}{2} \times (b_1 + b_2) \times h \]

where \( b_1 \) and \( b_2 \) are the lengths of the two bases and \( h \) is the height.

In your case:

  • \( b_1 = 24 \) cm (the length of the bottom base)
  • \( b_2 = 20 \) cm (the length of the top base)
  • \( h = 10 \) cm (the height)

Now plugging in the values:

\[ \text{Area} = \frac{1}{2} \times (24 \text{ cm} + 20 \text{ cm}) \times 10 \text{ cm} \]

\[ = \frac{1}{2} \times 44 \text{ cm} \times 10 \text{ cm} \]

\[ = \frac{1}{2} \times 440 \text{ cm}^2 \]

\[ = 220 \text{ cm}^2 \]

So, the area of the trapezoid is 220 cm².
