In a rectangle, there are a few statements that are always true. Opposite sides are congruent and parallel and all angles meet at 90 degrees. However, adjacent sides (sides that are touching/share a vertex) are not necessarily congruent. They can be; if they are then that rectangle is a square. Nevertheless, if adjacent sides are not congruent, then it is still a rectangle, so long as they meet at a right angle.
So, to solve this, we use this equation: 3700 + 0.05(3700) But, if we want to make it shorter: 1.05(3700) Now you just multiply(you may want to use a calculator) 1.05(3700) = 3885 She will pay $3885
