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 total length we can find the total width.

See as follows,

103.6 - 78= 25.6

2 widths= 25.6

1 width= 25.6÷2

=12.8 In

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.
