write the following sets by listing its elements.
a = {n ∈ \mathbb{n} : n > 10}
b = {m ∈ \mathbb{z} : \left | m \right | ≤ 4}
c={x∈\mathbb{r}: x2+2x+2=0}
d={x∈\mathbb{r}: x2+2=0}

A = {11, 12, 13, 14, 15, }

B = {-4, -3, -2, -1, 0, 1, 2, 3, 4}

C = {}

D = {}

Step-by-step explanation:

A is just natural numbers greater than 10 so it's 11, 12, and so on.

B is an integer between -4 and 4 inclusively. |m| ≤ 4 is same as -4 ≤ m ≤ 4

C and D is quadratic equation with no real solution, and since the set must be in real numbers, C and D are both empty set.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
