Question

SONI is a rectangle. What is the length of IN ?​

Answer 1

Answer:

since it is a rectangle therefore it's opposite sides are equal

therefore

5x=3x+18

5x-3x=18

2x=18

x=9

now putting the value of x in on side

i.e. 5x

=5×9

=45

therefore the length of the rectangle is 45

Answer 2

Answer:

45 Units

Step-by-step explanation:

Opposite sides of a Rectangle are same

Therefore 3x+18 = 5 X

                       18= 5x-3x

                        18= 2x

Therefore       x = 9

substitute value of x

Length of NI = 3X + 18

                        3 (9)+18

                       27+18

                       45
