# The perimeter of the figure ABCDEFGHIJ is

(a) 60 cm

(b) 30 cm

(c) 40 cm

(d) 50 cm

**Solution:**

We have to find the perimeter of the figure ABCDEFGHIJ

Perimeter = sum of all sides

So, perimeter = AB + BC + CD + DE + EF + FG + GH + HI + IJ + AJ

From the figure,

DE = BC + AJ +& IH + FG

Now, perimeter = 6 + BC + 4 + 20 + 2 + FG + 5 + 3 + AJ

= 6 + 4 + 20 + 2 + 5 + 3 + BC + FG + AJ

= 10 + 20 + 10 + DE

= 20 + 20 + 20

= 60 cm

Therefore, the perimeter of the given figure is 60 cm.

**✦ Try This****: **Find the perimeter of the rectangle with length 10 cm and breadth 8 cm.

Given, length and breadth of the rectangle are 10 cm and 8 cm.

We have to find the perimeter of the rectangle

Perimeter of rectangle = 2(length + breadth)

= 2(10 + 8)

= 2(18)

= 36 cm

Therefore, the perimeter of the rectangle is 36 cm.
