Answer:
It is not a rectangle
Step-by-step explanation:
A rectangle is a shape with 4 sides, such that we have two pairs of parallel sides, where the length of the parallel sides is equal.
so we have two parallel sides with length L and two parallel sides with length L'.
In this figure ,we can see two sides with length 20 and other two with length 21, and this is a rectangle only if the sides meet at 90°degree angles (this would mean that the opposite sides are parallel)
To see this, we can think that the triangle formed by the diagonal and two sides is a triangle rectangle, then using the Pythagorean theorem we should have that:
20^2 + 21^2 = 28^2
841 = 784
So this is not a triangle rectangle, meaning that the angle between the side of 20 and the side of 21 is not a right triangle, then the figure is not a rectangle.
Therefore, it is not a rectangle

Answer:
$191.25
Step-by-step explanation:
To find the price after the discount you will need to turn the percentage into a decimal. Since 1 represent as a 100% we will subtract 15% percent from it. To do this we will divide 15 by 100 to get .15. Subtract .15 from 1. This will give you .85. With .85 you multiply it by the original price of the shoes ($225). This will give you 191.25.
Since the triangles are similar, the answer is p : a
