Question

find the area of the
faces of the prism.
what is the area of
rectangle 2? (x2)
rectangle 1 (x2): 48 ft2
rectangle 2 (x2): ? ft2

Explanation:

Step1: Determine the dimensions of rectangle 2

From the given prism, rectangle 2 has dimensions \(15\) ft (height) and \(3\) ft (width).

Step2: Calculate the area of one rectangle 2

The area formula for a rectangle is \(A = l\times w\). For rectangle 2, \(A = 15\times3=45\) \(ft^{2}\).

Step3: Calculate the area of two rectangle 2s

Since we need to find the area of two such rectangles, we multiply the area of one by 2. So \(45\times2 = 90\) \(ft^{2}\).

Answer:

\(90\) \(ft^{2}\)
