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

Answer:

Perimeter of square Q is 49 inches.

Step-by-step 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 :

$\frac{x}{y}=\frac{2}{7}$

Also it is given that x=3.5 inches.Hence

$\frac{3.5}{y}=\frac{2}{7}$

∴ y=12.25 inches.

Perimeter of square Q is 4y = $4\times12.25=49$ inches.
