How to find perimeter of a figure?
The perimeter of the shape of the hand glider is the sum of the whole sides. Therefore,
Let's find the length of the two upper side using pythagoras theorem.
(0, 2)(12, 7)
Hence,
d = √(7 - 2)²+(12 - 0)²
d = √5² + 12²
d = √25 + 144
d = √169
d = 13 ft
Therefore,
perimeter = 13 + 13 + 2 + 2 + 24 = 54 ft
