[tex]Area=l*w\\Area=4units*3units\\Area=12units^{2}[/tex]

Answer:
Step-by-step explanation:
Below are the dimensions of the rectangle and the crossed portions are unwanted regions.
A.
Rectangle A:
Length, l = 3 units
Width, b = 2 units
Area of a rectangle = length × width
= 3 × 2
= 6 units^2
B.
Rectangle B:
Length, l = 3 units
Width, b = 2 + 1/2 units
= 5/2 units
Area of a rectangle = length × width
= 3 × 5/2
= 15/2 units^2
C.
Rectangle C:
Length, l = 5 units
Width, b = 1 + 1/2 units
= 3/2 units
Area of a rectangle = length × width
= 5 × 3/2
= 15/2 units^2
D.
Rectangle D:
Length, l = 2 units
Width, b = 1 + 3/4 units
= 7/4 units
Area of a rectangle = length × width
= 2 × 7/4
= 7/2 units^2
E.
Rectangle E:
Length, l = 5 units
Width, b = 3/4 units
= 3/4units
Area of a rectangle = length × width
= 5 × 3/4
= 15/4 units^2
