1 answer

To find the area of the trapezoid, you need two bases and the height. However, the dimensions given (2 cm, 7 cm, and 16 cm) do not specify which are the bases and what the height is. In a trapezoid, the two bases are usually the parallel sides, and the height is the perpendicular distance between these bases.

Assuming:

  • Base 1 = 2 cm
  • Base 2 = 7 cm
  • Height = 16 cm

Using the area formula for a trapezoid:

\[ \text{Area} = \frac{(Base¹ + Base²)}{2} \times Height \]

Substituting the values:

\[ \text{Area} = \frac{(2 , \text{cm} + 7 , \text{cm})}{2} \times 16 , \text{cm} \] \[ = \frac{9 , \text{cm}}{2} \times 16 , \text{cm} \] \[ = 4.5 , \text{cm} \times 16 , \text{cm} \] \[ = 72 , \text{cm}² \]

Thus, the area of the trapezoid is:

\[ \boxed{72 , \text{cm}²} \]
