Answer:
<em>Number of story books bought = 100
</em>
<em>
C.P. of each book = Rs. 135
</em>
<em>
C.P. of all 100 books = Rs. (135×100)= Rs. 13500
</em>
<em>
C.P. of 90 books = Rs. (135×90)= Rs. 12150
</em>
<em>
Number of books donated = 10
</em>
<em>
Number of books sold = 100-10=90
</em>
<em>
Loss% in the transaction = 2%
</em>
<em>
S.P. of all books = (C.P./100)(100-loss%)
</em>
<em> =Rs. (12150/100×98)
</em>
<em>
Thus, S.P. of each book
</em>
<em>
= Rs. {(12150/100×98)÷90}
</em>
<em>
= Rs. (12150/100×98/90)
</em>
<em>
= Rs. 132.3</em>
The perimeter of the figure is 20.73 cm.
<h3>What is perimeter:</h3>
Perimeter is a closed part that surrounds a two dimensional or one length figure.
The perimeter of the figure above is the sum of the wholes sides. In other word the sum that surrounds the whole sides.
Therefore, the perimeter of the figure is as follows:
perimeter = 3.1 + 5.2 + 4.24 + 2.19 + 6
perimeter = 8.3 + 4.24 + 2.19 + 6
perimeter = 12.54 + 2.19 + 6
perimeter = 14.73 + 6
perimeter = 20.73 cm
Therefore, the perimeter of the figure is 20.73 cm.
