Question

Square P and Sqare Q are similar squares. The ratio of the side length of square P to the side length of square Q is 2:7. If the side length of square P is 3.5 inches, what is the perimeter of square Q

Answer 1

Perimeter of square Q is 49 inches.

Explanation:

Let x be the length of side of square P and y be that of square Q.

It is given in the question that :

`(x)/(y)=(2)/(7)`

Also it is given that x=3.5 inches.Hence

`(3.5)/(y)=(2)/(7)`

∴ y=12.25 inches.

Perimeter of square Q is 4y =
`4*12.25=49` inches.
