CPM Homework Help : CCG Problem 11-123

Multiple Choice: The Mona Lisa, by Leonardo da Vinci, is arguably the most famous painting in existence. The rectangular artwork, which hangs in the Musée du Louvre, measures $77$ cm by $53$ cm. When the museum created a billboard with an enlarged version of the portrait for advertisement, they used a linear scale factor of $20$ . What was the area of the billboard?

$4081 \;\text{cm}^2$

$32\text{,}638\text{,}000\;\text{cm}^2$

$81\text{,}620\;\text{cm}^2$

$1\text{,}632\text{,}400\;\text{cm}^2$

None of these

Hint:

$\text{Area of the billboard}=\left(\text{area of the original painting}\right)\left(20\right)^2$
