Given
Drawing
1. What is the area of the board shown on the scale drawing?
The area is equal to 1800. Since it is a rectangle you can calculate the area by multiplying its sides.
A = 50*36 = 1800 sq cm
2. What is the area of the actual electronics board?
Let's calculate the actual dimensions of the electronic card using the scale factor
Sides
[tex]\begin{gathered} 50\cdot\frac{1}{5}=10 \\ 36\cdot\frac{1}{5}=7.2 \end{gathered}[/tex]The actual area is calculated by multiplying these new dimensions
A = 10*7.2
A = 72
The area of the electronic card would be 72 square centimeters.
