Can someone me figure this out on the attachment

The rectangle:
l*w=area The length is 12 and the width is 5. So 5*12=60. The area of the rectangle is 60
The triangle:
l*w/2=area The length is 6 and the width is 2. To figure out the width you have to subtract the 5 and 5 from the top dimension. 6*2/2=6
All together: 60+6=66

Its 45in² because you have to plus all the sides.

Add the cents that add the left overs to get the first number
