Answer:
A = 35 square units
Step-by-step explanation:
Formula to calculate the distance between two points
and
is,
d = 
Length of the segment between A(2, 2) and B(9, 2) =
= 7 units
Length of the segment between B(9, 2) and C(9, -3) = 
= 5 units
Length of the segment between C(9, -3) and D(2, -3) = 
= 7 units
Length of the segment between A(2, 2) and D(2, -3) = 
= 5 units
Therefore, given polygon is a rectangle.
Area of the rectangle = length × width
= 7 × 5
= 35 square units
