A rectangle has a perimeter of 103.6 inches and a base of 39 inches. What is the height?
rusak2 [61]

Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the <u>total</u><u> </u><u>length</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>find</u><u> </u><u>the</u><u> </u><u>total</u><u> </u><u>width</u><u>.</u>

See as follows,

103.6 - 78= 25.6

<u>2</u><u> </u><u>widths</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u>

<u>1</u><u> </u><u>width</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u><u>÷</u><u>2</u>

<u>=</u><u>12</u><u>.</u><u>8</u><u> </u><u>In</u>

Devon says that triangles TUV and XYZ are similar because TU/XY UV/YZ XZ/TV what is wrong with his reasoning?
jeka57 [31]

Answer:

Devon use \frac{XZ}{TV} instead of \frac{TV}{XZ} in his reason. So, we can say that triangles are not similar.

Step-by-step explanation:

If two triangles are similar then their corresponding sides are proportional.

If triangle TUV and XYZ are similar, then

\frac{TU}{XY}=\frac{UV}{YZ}=\frac{TV}{XZ}

The reason given be Devon is

\frac{TU}{XY}=\frac{UV}{YZ}=\frac{XZ}{TV}

He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use \frac{XZ}{TV} instead of \frac{TV}{XZ} in his reason.

Therefore his reason is incorrect. So, we can say that triangles are not similar.
