Question

Arrange the perimeters of the following polygons in descending order.

Answer 1

● Perimeter of a closed figure = Sum of the lengths of all sides
For figure P:
● Perimeter of figure P $=6+10+8$
● Perimeter of figure P $=24$ ft
For figure Q:
● Perimeter of figure Q $=6+3+14+2$
● Perimeter of figure Q $=25$ ft
For figure R:
● Perimeter of figure R $=9+10+7+10$
● Perimeter of figure R $=36$ ft

Therefore, Perimeter of R > Perimeter of Q > Perimeter of P

Hence, option D is the correct answer.
