If condition is true return sumproduct of two arrays
 

I need to resolve the following:

Column F contains different states, one in each row: FL, CA, NY...
Columns G and H contain values

I need to display in a destination cell the sumproduct of all G and H where
F=Florida, in other words, if only F3 and F4 equals Florida, I need
G3*H3+G4*H4.

Appreciate any help,
