Answer:

$\huge\boxed{\sf 18 cm\²}$

Step-by-step explanation:

The figure consists of 2 rectangles.

<u>Rectangle 1 Area:</u>

Length = 5 cm

Width = 2 cm

Area = Length * Width

A = 5 * 2

A = 10 cm²

<u>Rectangle 2 Area:</u>

Length = 4 cm

Width = 2 cm

Area = 2 * 4

A = 8 cm²

<u>Area of the whole figure:</u>

= Rectangle 1 + Rectangle 2

= 10 + 8

= 18 cm²

$\rule[225]{225}{2}$

Hope this helped!
