D = {x|x is a whole number}
pickupchik [31]

The given statement is true.

Step-by-step explanation:

Given sets are:

D = {x|x is a whole number}

E = {x|x is a perfect square between 1 and 9}

F = {x|x is an even number greater than or equal to 2 and less than 9}

as the sets are given in set builder notation,, we will first write the sets in set notation.

So,

D = {0,1,2,3,4,...}

E = {4,9}

F = {2,4,6,8}

Now,

EUF = {4,9} U {2,4,6,8}

= {2,4,6,8}

Hence,

The given statement is true.

Area of the bigger trapezoid = (6 + 2) x 1/2 x 6 = 8 x 1/2 x 6 = 4 x 6 = 24

Area of the smaller trapezoid = (4 + 2) x 1/2 x 3 = 6 x 1/2 x 3 = 3 x 3 = 9

<h2>Area of the shaded area = 24 - 9 = 15</h2>
