Question

a1 = __ × __
a2 = __ × __
total area = ____
also find the perimeter ____

Explanation:

Step1: Calculate area of first rectangle

The first rectangle has length \(4m\) and height \(8m\).
\(A1 = 4\times8\)

Step2: Calculate area of second rectangle

The second rectangle has length \(10m\) and height \(10m\).
\(A2 = 10\times10\)

Step3: Calculate total area

\(Total\ Area=A1 + A2=(4\times8)+(10\times10)=32 + 100=132m^{2}\)

Step4: Calculate perimeter

The figure's perimeter: sum of all outer - sides.
\(Perimeter=8 + 4+10+10+(10 - 8)+(4 + 10)=8+4 + 10+10+2+14 = 48m\)

Answer:

\(A1 = 4\times8\); \(A2 = 10\times10\); \(Total\ Area = 132m^{2}\); \(Perimeter = 48m\)
