Question

a1 = _ × _
a2 = _ × _
total area = _

Explanation:

Step1: Calculate the area of the first rectangle

The first rectangle has length \(4m\) and width \(8m\). The area formula for a rectangle is \(A = length\times width\). So \(A1 = 4\times8\).

Step2: Calculate the area of the second rectangle

The second rectangle has length \(20m\) and width \(8m\) (since the total height is \(8m\) for the first part and they are at the same height level). The area formula for a rectangle is \(A=length\times width\). So \(A2 = 20\times8\).

Step3: Calculate the total area

The total area \(A = A1+A2\). Substitute \(A1 = 32\) (\(4\times8 = 32\)) and \(A2=160\) (\(20\times8 = 160\)) into the formula. So \(A=32 + 160\).

Answer:

\(A1 = 4\times8\); \(A2=20\times8\); Total Area \(=192m^{2}\)
