Question

determining the missing lengths of a scale drawing
consider the enlargement of the triangle with a scale factor of 8
side a = 2(8) = 16 cm.
what is the length of side b?

Explanation:

Step1: Determine the scale factor

The original side length is \(8\) cm and the new side length is \(64\) cm. The scale factor \(k=\frac{64}{8} = 8\)

Step2: Calculate the length of side B

The original side length corresponding to side B is \(5\) cm. Using the formula for scale - factor \(new\ length=k\times original\ length\), we have \(B = 8\times5\)

Answer:

\(40\) cm
