The bottom trapezoid is
(1/2) * h * (b2 + b1) =
(1/2)*11 * (31+25)
(1/2) * 11 * 56
308
The top parallelogram is
b * h = 12 * 14 = 168
308 +168 = 476 ft^2

A rigid motion is any motion that doesn't deform the original shape - it's a motion that preserves the lengths and angles of a shape without stretching, squishing, or bending anything. The best way to think about rigid motions is to imagine holding something solid in your hand, like a smartphone. How can you move it around? You can <em>rotate</em> it around in your hand, changing its orientation; you can move your hand around through space, changing the smartphone's position. While it may not seem like a motion, you can also hold it up to a mirror, <em>reflecting </em>it in some way. These three transformations, rotation, translation (shifting position), and reflection, are the three primary rigid motions.
There are 10 bird feeders in total. So if Bob builds 10 Jake builds 0. If Bob builds 9 then Jake builds 1. If Bob builds 8 then Jake builds 2 and so on.
C because you need to multiply the adults by 3 to know how many children there are and then you need to exclude the driver which is a-1 meaning taking out 1 adult.
