262,144 feet squared
This seems like a big number but area length times width. If the coaster is square then all sides are the same so the length and width are both 512 feet. This means you multiply 512 and 512. With that you get 262,144 feet squared.

A. Randomized block design
Step-by-step explanation:
A randomized block design is one where the sample or subjects of the experiment are split into groups called blocks of experimental units where the variation in each block is lower than the variation among or between blocks, such that variation is controlled. In a random order, the treatments are performed on each experimental of the blocks.
In the question, the experimental units are grouped by gender and the treatment (consumption of chocolate or placebo) is randomly administered to the experimental units.
