Question

line QR, line RS and line SQ are midsegments of triangle WXY. The perimeter of WXY is ____ cm.

Answer 1

Answer: 14.5 cm

Step-by-step explanation:

• The mid point theorem says that if line joining the midpoints of the any two sides , then this line becomes parallel to the third side and it becomes half of the third side.

Here , if consider firstly Q and R are mid-points of XW and XY then,

QR║WY such that

$WY=\timesQR=2\times2.93=5.86\ cm$

Similarly, RS║XW such that

$XW=2\timesRS=2\times2.04=4.08\ cm$

Similarly, QS║XY such that

$XY=2\timesQS=2\times2.28=4.56\ cm$

Now, the perimeter of the triangle= $WY+XW+XY=5.86+4.08+4.56=14.5\ cm$
