X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:
P= 2L + 2W and A= L x W
P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)
P= 12.8 cm
A= 3.2 x 3.2
A= 10.24 cm^2
So for x:

For y:
