Find the area.

a = [?]cm²
2 cm, 7 cm and 16 cm
Shape: Trapezoid
Area of a trapezoid: (Base¹ + Base²)/2 x Height
Base: 7
Height: 16

1 answer

To find the area of a trapezoid using the formula:

\[ \text{Area} = \frac{(Base_1 + Base_2)}{2} \times Height \]

we need to identify the two bases and the height. Given:

  • Base 1 (Base_1) = 7 cm
  • Base 2 (Base_2) = 2 cm
  • Height = 16 cm

Now, we can plug these values into the formula:

\[ \text{Area} = \frac{(7 , \text{cm} + 2 , \text{cm})}{2} \times 16 , \text{cm} \]

Calculating the sum of the bases:

\[ 7 + 2 = 9 , \text{cm} \]

Now substitute into the area formula:

\[ \text{Area} = \frac{9 , \text{cm}}{2} \times 16 , \text{cm} \]

\[ = 4.5 , \text{cm} \times 16 , \text{cm} \]

\[ = 72 , \text{cm}^2 \]

Thus, the area of the trapezoid is

\[ \boxed{72} , \text{cm}^2 \]
