Answer:

The second base of the trapezoid b2 is 2.5 inches

Step-by-step explanation:

Here, we want to calculate the second base of the trapezoid.

Mathematically, the area of a trapezoid can be given as;

A = 1/2(a + b) h

where a and b represents the parallel bases and h is the height of the trapezoid

so this, we have from the question

1/2(4.5 + b2) * 6 = 21

3(4.5 + b2) = 21

divide both sides by 3

4.5 + b2 = 7

b2 = 7-4.5

b2 = 2.5 inches

Answer:  \textsf{Option A, 13}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{Side length = 9 units}

Find:  \textsf{Diagonal length}

Solution:  The diagonal length can be easily determined using an equation which uses the side length of a square multiplied by the square root of 2. All we need to do is plug in the values and simplify the expression.

<u>Plug in the values</u>

  • \textsf{Diagonal = Side length} * \sqrt{2}
  • \textsf{Diagonal = 9 units} * \sqrt{2}

<u>Simplify the expression</u>

  • \textsf{Diagonal = 9 units * 1.4142}
  • \textsf{Diagonal = 12.73 units}

Looking at the answer options that have been provided, the option that best fits our scenario is option A, 13.
