. Wi. Re. Lesson ao d. The figures shown are regular pentagons, meaning that each pentagon has five sides that are the same length. If a side length of figure 1 is 40 units, what is the length of the corresponding side of figure 3 ?

a. Is figure 3 a scale drawing of figure 1 ?

Na figura está representado um cubo. Determina a medida da aresta, em centímetros, 7.1. a área da superficie total do cubo for \( 726 \mathrm{~cm}^{2} \);

b. What scale factor reduces figure 1 to figure 3 ?
