following activity​

Answer 1

Answer:

Given: X and Y are mid points of AB and AC respectively.

In △ABC, using mid point theorem

XY∥BC and XY=

BC

Thus, XY=3 cm

Since, D is mid point of AB , BX=

AB=

(5.4)=2.7 cm

Also, E is mid point of AC, CY=

AC=

(5)=2.5 cm

Now, Perimeter of XYCB = XY+YC+BC+XB

Perimeter of XYCB = 3+2.5+6+2.7

Perimeter of XYCB = 3+2.5+6+2.7 = 14.2 cm
