Qr, rs , and sq are midsegments of wxy.

the perimeter of wxy is cm.

Perimeter of ΔWXY is given by

Step-by-step explanation:

Since we have given that

By using Mid point theorem, "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".

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

QR║WY so,

Similarly,

QS║XY so,

Similarly,

RS║XW, so

Perimeter of ΔWXY is given by
