Question

Can anyone help and let me know if this is the correct answer

Answer 1

Yep. I think there was a misprint or typo on the page that made the area say 142.5 twice. It is only supposed to be once.

To get the answer for this equation...

142.5/15=

9.5

The width is 9.5.

To check do 9.5*15


(Which equals 142.5 for area)
