Answer 1

Answer:

According to the question

As SONI is a rectangle, opposite sides are equal

IN=SO

3x+18=5x

18=5x-3x

18=2x

x=9

So, IN=3x+18

=3(9)+18

=27+18

=45 units

Answer 2

Answer:

$\huge\orange{ \mid{ \underline{ \overline{ \tt x = 9}} \mid}}∣$

option (4) is correct

$\huge\orange{ \mid{ \underline{ \overline{ \tt lengh IN= 45}} \mid}}∣$

Step-by-step explanation:

since SONI. is a rectangle then,

opposite sides are equal

3x +18=5x

18 = 5x -3x

18= 2x

x = 18/2

x = 9

Ans

lengh IN = 3x +18

= 3(9)+ 18

= 45
