Answer

(b)
Image
∴ Length of boundary = AB + BC + CD + DE + EF + FG + GA
= 6 + 2 + 6 + 2 + 4 + 6 + 2
= 28 cm
(c)
Image
Total length of boundary = AB + BC + CD + DE +EF + FG + GH + HA
= 2 + 6 + 2 + 2 + 6 + 2 + 6 + 2
= 28 cm
(d)
Image
Total length of boundary = AB + BC + CD + DE + EF + FG + GH + HA
= 6 + 2 + 3 + 2 + 6 + 2 + 3 + 2
= 26 cm

In the following figure numbers are written in the boxes in three columns. Arrows are directed towards the first and third columns from the boxes in the second column. The number in the box in first or third column is sum of the numbers in the middle row from which arrows originate.
For example,
$\begin{array}{l}3,400=1,500+1,500+400 \\ 38,800=25,000+400+400+13,000\end{array}$
Image
Similarly, draw arrows from the boxes in the middle column to the numbers on the side columns to obtain the following sums: $14,000,\ 25,000,\ 16,000$
Can we make 1,000 using the numbers in the middle column?
