Step-by-step explanation:

Plotted the given points to find out the figure is trapezoid.

Area formula for trapezoid:

A = 1/2(b₁ + b₂)h

The length of the bases:

b₁ = DE = 3 - (-1) = 4
b₂ = FG = 4 - (-3) = 7

h is the horizontal distance between the bases:

h = 2 - (-1) = 3

The area is:

A = 1/2(4 + 7)(3) = 16.5 unit²
