Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e 4 : 1.
| Understanding/Application |
|
Let the length of the side of the two squares be x and y respectively. The ratio of the area of two squares = 16 : 1 |
|
a2/b2 = 16/1 (a/b)2 = (4/1)2 a/b = 4/1 4a/4b = 4/1 Thus, the ratio of perimeters = 4 : 1 |
