problems 2 - 4: leonardo da vincis famous painting, the mona lisa measures 21 inches by 30 inches.\n2. create a scale drawing of the outline of the mona lisa where 1 unit represents 3 inches.\n3. create a scale drawing of the outline of the mona lisa where 2 units represents 5 inches.

Answer

Explanation:

Step1: Calculate scale - drawing dimensions for 1 unit = 3 inches

For the width of 21 inches, the number of units is $\frac{21}{3}=7$. For the height of 30 inches, the number of units is $\frac{30}{3}=10$.

Step2: Calculate scale - drawing dimensions for 2 units = 5 inches

First, find the number of 5 - inch segments. For the width of 21 inches, the number of 5 - inch segments is $\lfloor\frac{21}{5}\rfloor = 4$ (with a remainder). Since 2 units represent 5 inches, the number of units for width is $2\times4 = 8$. For the height of 30 inches, the number of 5 - inch segments is $\frac{30}{5}=6$, and the number of units for height is $2\times6 = 12$.

Answer:

For 1 unit represents 3 inches: Width = 7 units, Height = 10 units. For 2 units represents 5 inches: Width = 8 units, Height = 12 units.
