G
F

Step-by-step explanation:

Given

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;

In this case;

Substitute the values of Area, HE and EF

Divide both sides by 4

Subtract 12 from both sides

Hence, the length of HG is 5mm
