Answer:
[tex]18 {m}^{2} [/tex]
Step-by-step explanation:
The figure shown in the image is a parallelogram.
To find the area of a parallelogram we use the following formula:
A = b • h (b: base, h: height)
The height is 4.5m while the base is given as 4m
(4.5) • 4 = 18
Since the area is put in square units the answer is
[tex]18 {m}^{2} [/tex]
