Answer 2

The perimeter of the remaining portion is 114 cm.

Step-by-step explanation:

Consider the provided information.

The side of the equilateral triangle is 40 cm.

An equilateral triangle with 6 cm is removed.

Consider the figure shown below.

If an equilateral triangle with 6 cm removed then the length of two sides must decreased by 6 cm.

40 cm - 6 cm = 34 cm

So, now the measures of the sides are: 34 cm, 34 cm, 40 cm and 6 cm.

(For better understanding refer the figure)

Perimeter is the sum of all sides.

P=34+34+40+6=114

Hence, the perimeter of the remaining portion is 114 cm.
