$\text{Hello there!}\\\\\text{We're trying to find the area of the shape}\\\text{We can do this by finding the area for the different shapes, then adding}\\\text{them together}\\\\\text{We can find the area of the rectangle,} \,\,84\cdot66=5,544\\\\\text{To find the area of the half circle, we would use the equation:}\,\,A=\frac{3.14r^2}{2}\\\\\text{The radius is half of the diameter, therefore it is 33. Plug 33 in r}\\\\A=\frac{3.14(33)^2}{2}\\\\\text{Solve:}\\\\A=\frac{3.14(33)^2}{2}\\$

$A=\frac{3.14(1089)}{2}\\\\A=\frac{3419.46}{2}\\\\\text{Divide by 2}\\\\A=1709.73\\\\\text{Since there's two half circles, we would add 1709.73 twice}\\\\\text{Add all the areas together}\\\\1709.73+1709.73+5,544=8963.46\\\\\large\boxed{\text{Area:}\,\,8963.46\,\,\text{m}^2}}$

Murrr4er [49]

The four books had an average of 341 pages

Step-by-step explanation:

Given

Total number of books = 4

Pages in first book = x1 = 326

Pages in second book = x2 = 288

Pages in third book = x3 = 349

Pages in fourth book = 401

The average is given by:

$Average=\frac{Sum\ of\ pages}{number\ of\ books}\\=\frac{x_1+x_2+x_3+x_4}{4}\\=\frac{326+288+349+401}{4}\\=\frac{1364}{4}\\=341$

The four books had an average of 341 pages
