The lateral area is the same as the as the surface area without the area of the bases.
In this solid, the bases are the 14 by 7 rectangles, so those are the only 2 sides that will be excluded in the lateral area.
Add the areas of the other rectangles except those two to find the lateral area.
The lateral area is 69.72 square centimeters.
We already have the lateral area, so finding the total surface area will be quite simple. Just find the area of the two bases and add them to the lateral area.
The total surface area is 265.72 square centimeters.
Rounding everything, the answer is 70 cm² and 266 cm² (last answer choice). Hope this helps! :)
