Answer:
Perimeter of Square Q = 49
Step-by-step explanation:
given:
sides P:Q = 2:7
side length of P = 3.5.
First, determine length of side Q by using the ratio
[tex]\frac{2}{7}=\frac{3.5}{side Q}\\side Q = \frac{7*3.5}{2}[/tex]
The perimeter is 4 times the length of the side
So, Perimeter of square Q = 4 *(7*3.5)/2 = 49
