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

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 \(A = l\times w\). So, \(A=15\times3 = 45\) \(ft^{2}\).

Step3: Calculate the area of two rectangle 2s

Since we need to find the area for two such rectangles (as indicated by \((x2)\)), we multiply the area of one by \(2\). So, \(45\times2=90\) \(ft^{2}\).

Answer:

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