Perimeter of a 9-9-17-10 trapezoid
How it works.
sides:991710
sides:991710

9 + 9 + 17 + 10=45 cm
- 01
Perimeter is the distance around the outside — like the length of a fence around a field.
- 02
Walk around the edge and add the sides: 9 + 9 + 17 + 10.
- 03
9 + 9 + 17 + 10 = 45 cm. It is a length, so the unit is cm, not square cm.
