Question

your aunt bought a new truck. the drivers side window is a trapezoid.
in trapezoid trck:

  • \\(\overline{tr}=21.7\\) inches
  • \\(\overline{kc}=27.1\\) inches
  • \\(\overline{tk}=12.8\\) inches
  • \\(\overline{rc}=11.6\\) inches

what is the area of the car window?
use the given information to complete the worksheet.

area formulas:

  • parallelogram: \\(a = bh\\)
  • square: \\(a = s^{2}\\)
  • triangle: \\(a=\frac{1}{2}bh\\)
  • trapezoid: \\(a = \frac{1}{2}h(b_1 + b_2)\\)

Explanation:

Step1: Identificar fórmula

La fórmula para el área de un trapecio es $A=\frac{1}{2}h(b_1 + b_2)$. Aquí, $h$ es la altura, $b_1$ y $b_2$ son las bases.

Step2: Asignar valores

La base más larga $b_1 = 27.1$ pulgadas, la base más corta $b_2 = 21.7$ pulgadas y la altura $h = 11.6$ pulgadas.

Step3: Calcular área

Sustituir valores en la fórmula:
\[

$$\begin{align*} A&=\frac{1}{2}\times11.6\times(27.1 + 21.7)\\ &= 5.8\times48.8\\ &=283.04 \end{align*}$$

\]

Answer:

283.04 square inches
