Question

Same question, but I want different people to answer so I understand how you got it.
Please explain how you got it

Answer 1

Answer:

6/10=9/y

y=90/6

y=15 ...........

..

Answer 2

y=5

Step-by-step explanation:

the perimeter of rectangle =2(l+b)

in the first rectangle, the perimeter =2(9+6)

=2(15)

in the second rectangle the perimeter =2(10+y)

therefore 2(15)=2(10+y)

both the 2 get canceled

so, 15=10+y

y=15-10

therefore, y=5
