Question

find the surface area of the triangular prism.
now, find the area of the rectangles.
(formula: a = lw)
area of both triangles: 36 cm²
area of the bottom rectangle: ? cm²

Explanation:

Step1: Identify length and width

The bottom rectangle has length \( 6 \, \text{cm} \) and width \( 9 \, \text{cm} \) (from the prism's dimensions).

Step2: Apply area formula for rectangle

Using the formula \( a = lw \), where \( l = 6 \) and \( w = 9 \).
\( a = 6 \times 9 \)
\( a = 54 \)

Answer:

\( 54 \, \text{cm}^2 \)
