Adam can use the scale factor to find the area of the actual electronics board by squaring the scale factor.
If the electronics board is drawn to a scale of 1:5, this means that every dimension of the drawing is 1/5th the size of the actual board. Therefore, the scale factor is 5.
To find the area of the actual board, Adam can take the area of the drawing and multiply it by the square of the scale factor. For example, if the area of the drawing is 20 square inches, then the area of the actual board would be:
20 x 5^2 = 500 square inches
So, Adam can use the scale factor to find the area of the actual board by multiplying the area of the drawing by the square of the scale factor.
Hope this helps!!!:)
