Answer:

215.6 cm^2

Explanation:

The top and bottom "wings" are 3.25 cm by 12.25 cm, so each has an area of ...

A = LW

A = (12.25 cm)(3.25 cm) = 39.8125 cm^2

The left and right "wings" are 3.25 cm by 7.25 cm, so each has an area of ...

A = (7.25 cm)(3.25 cm) = 23.5625 cm^2

The middle rectangle is 12.25 cm by 7.25 cm, so its area is ...

A = (12.25 cm)(7.25 cm) = 88.8125 cm^2

Then the total area is ...

area = middle rectangle + 2×side wings + 2×top/bottom wings

= 88.8125 +2(23.5625) +2(39.8125) = 215.5625 . . . cm^2

The area of the figure is about 215.6 cm^2.
