romanna [79]

Answer:

Step-by-step explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

$\begin{array}{rcl}AB & = & \frac{1}{2}(JK + LM)\\\\& = & \frac{1}{2}(19 + 39)\\\\& = & \frac{1}{2}\times 58\\\\& = & \mathbf{29}\\\end{array}$

The second floor of a tiny house has a living room in a bedroom. The floor plan shows a width of 8 ft in a total length of 24 ft

Keith_Richards [23]

Answer:

Expression 8 • 24 represents the total area.

Option A is correct.

Step-by-step explanation:

Width of living room = 8 ft

Length of living room = 24 ft

We need to calculate area:

The formula used is: $Area=Length \times Width$

Putting values to get the expression

$Area = 8\times24$

So, Expression 8 • 24 represents the total area.

Option A is correct.
