Question

6. The ratio of the areas of two squares is 9:16, then ratio of their perimeters is
a) 4:3
b) 3:4
c) 81:256
d) 3:8​

Answer 1

Answer:

Step-by-step explanation:

Let the 2 squares be S1 and S2.

Area of S1/ Area of S2= 9/16

Area of square = (side)²

Thus,

Side 1/ Side 2= √9 /√16 = 3/4

Thus,

Perimeter ratio= 4 × side/ 4× side= 12/16 =3/4

The correct answer is option b
