Please someone help me!

Lola began to construct opposite a reduction FGHIJ of the polygon ABCDE where the segment FH corresponds to the segment AC.

1) determine the reduction ratio.
2) complete Lola's work using the grid.
3) calculate the area of ​​the polygon ABCDE knowing that a square measures 5 mm on a side.
4) deduce the area of ​​FGHIJ.​​
