Answer:

Rectangle A: 22 cm

Rectangle B: 25.8 cm

Step-by-step explanation:

To find the area, we multiply the size of the two sides.

8 x 2 = 16

3 x 2 = 16

Now, we have to add 16 and 6.

16 + 6 = 22

To find the area, we multiply the size of the two sides.

5.2 x 2 = 10.4

7.7 x 2 = 15.4

10.4 + 15.4 = 25.8

The answers are:

  • 22 cm
  • 25.8 cm

Hope this helps!
