Question

find the area of the faces of the prism. what is the area of rectangle 3? (x2) rectangle 1 (x2): 48 ft2 rectangle 2 (x2): 240 ft2 rectangle 3 (x2): ? ft2

Explanation:

Step1: Identify the dimensions of rectangle 3

Rectangle 3 has dimensions \(3\) ft (width) and \(15\) ft (length).

Step2: Calculate the area of one rectangle 3

The area formula for a rectangle is \(A = \text{length}\times\text{width}\). So, \(A = 3\times15=45\) \(ft^{2}\).

Step3: Calculate the area of two rectangle 3s

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

Answer:

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