A building casts a 50-foot shadow. Alex is 5 feet tall and casts a 6-foot shadow. Approximately how tall is the building?

Use ratios to solve this!

5:6 or 5/6 is the ration for Alex. 

<span>Cross multiplication is used to solve this, so: 
6x = 5(50) </span>
<span>6x = 250 </span>
<span>x = 250/6 </span>
<span>x = 41.67 which then rounds to 42 feet.

Also to your earlier question here is a screenshot of what the box should look like, and i have circled the attach file icon
