#P = 107# cm

The perimeter of any shape is the total distance along the sides.

Perimeter = side + side + side + side .....

A pentagon has 5 sides, therefore 5 lengths have to be added together.

You are given that 3 sides have the same length and the other 2 sides are equal in length.

#P = 26+26+26+14.5+14.5#

(add the lengths of 5 sides together)

Better: #P = 3 xx26+ 2 x14.5#

#P= 107 #cm
