What is the scale factor from ABC to DEF?

Mathematics
1 answer:
sdas [7]3 years ago
3 0

Within similar triangles, the angles are the same. So, we need to look at the side lengths then.

72 to 12

66 to 11

42 to 7

In each pair of corresponding side lengths, the original side length from triangle ABC is divided by 6 (or multiplied by 1/6) to get the smaller side length on triangle DEF.

The scale factor from ABC to DEF is 1/6.

Hope this helps!

a rectangle has a width of 8m and length of 7m how does the area change when each dimension is multiplied by 5
hichkok12 [17]

Answer:

The first thing we need to do is find the area of the rectangle...

<em>l x w = A</em>

<em>7 x 8 = 56</em>

So the area of the first rectangle is 56m.

Now we multiply each dimension by 5...

<em>8 x 5 = 40</em>

<em>7 x 5 = 35</em>

So, now the width is 40m and the length is 35m,

Then, find the area of the new rectangle...

<em>35 x 40 = 1400</em>

The area of this rectangle is 1,400m!

<em>1,400 / 56 = 25</em>

So, by multiplying each dimension by 5, the area is now multiplied by 25!
