Question

A perfect square that lies between 40 and 50 is:
A) 42
B) 45
C) 46
D) 49

Answer 1

Answer:

A perfect square that lies between 40 and 50 is 49.

Since, 1 × 1 = 1

2 × 2 = 4

3 × 3 = 9

4 × 4 = 16

5 × 5 = 25

6 × 6 = 36

7 × 7 = 49

Now, if we will do 8 × 8 then it's equal to 64 which is more than 50 and we also can't take take 6 × 6 because it results in 36 which is less than 40.

So, the result will be 49.

Step-by-step explanation:

Option (D) is correct.
