Perimeter and Area

• The perimeter of a closed figure is the distance covered along the boundary of the figure when we go around it once. Its units are cm, m etc.

Example: Let us find the perimeter of the following figure.

Perimeter of ABCDEFGHIJA = AB + BC + CD + DE + EF + FG + GH + HI + IJ + JA

= (5 + 6 + 6 + 5 + 7 + 9 + 7 + 4 + 4 + 25) cm

= 78 cm
