Question

(Geometry HELP) The perimeter of WXY is ___ cm?

Answer 1

Answer:

The perimeter of WXY is 14.5 cm

Step-by-step explanation:

Midpoint Theorem -

It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

From the picture, it can be observed that,

1. R is the midpoint of XY
2. S is the midpoint of YW
3. Q is the midpoint of XW

Applying the theorem,

1. XY=2SQ
2. YW=2QR
3. XW=2RS

Perimeter of WXY is,

$=XY+YW+XW$

$=2SQ+2QR+2RS$

$=2(SQ+QR+RS)$

$=2(2.28+2.93+2.04)$

$=2(7.25)$

$=14.5\ cm$

Answer 2

The answer is 29 first find the area of the smaller triangle and multiply by 4 since there are 4 of the smaller triangles in the bigger one
