## 28Tylerr Group Title Suppose the side lengths and height of the triangle were divided by three. What effect would this have on the perimeter? & The Area? Justify your answer @Geometry 2 years ago 2 years ago

1. 28Tylerr Group Title

The Orginial Perimeter was 33m and the Area was 27.

2. 28Tylerr Group Title

This is the last part of the question.

3. amistre64 Group Title

the perimeter is just like before; just divide it by 3; the area tho is nit a linear measurement and needs some work to it

4. 28Tylerr Group Title

P would equal 11?

5. 28Tylerr Group Title

Our base was 12? I think

6. amistre64 Group Title

12 sounds right, youd have to dbl chk tho :)

7. 28Tylerr Group Title

Our base was 12? I think

8. 28Tylerr Group Title

Here let me draw it out real quick (:

9. amistre64 Group Title

$Area = \frac{1}{2}*base*height$ $Area = \frac{1}{2}*\frac{base}{3}*\frac{height}{3}=\frac{1}{18}bh$

10. 28Tylerr Group Title

Our base was 12? I think

12. amistre64 Group Title

base = 6 and height = 9 it looks like in that

13. 28Tylerr Group Title

Our base was 12? I think

14. 28Tylerr Group Title

P = 1/2 x 54

15. 28Tylerr Group Title

A =*

if you just divided the measures in half, then your not matching this problem. It wants the measures divided by 3

18. amistre64 Group Title

12/3 = 4 18/3 = 6

19. 28Tylerr Group Title

20. amistre64 Group Title

i just checked out your other post; it was 6 for the bottom and 9 for the height ....

21. amistre64 Group Title

the normal area, is then: 1/2 x 54 as you stated

22. amistre64 Group Title

if we divide all the sides by 3; that will go to: 1/(2*3*3) x 54 or simply 1/18 x 54

23. amistre64 Group Title

which is also: 1/2 * 6/3 * 9/3 1/2 * 2 * 3 1/2 x 6

24. 28Tylerr Group Title

A = 3

25. amistre64 Group Title

yep

26. 28Tylerr Group Title

Man thanks your real good at this math.

27. amistre64 Group Title

we can say that if the sides are divided by 3, then the area is divided by 3^2
