**Author:** Akshay Venkataramani

**Tester:** Timothy Jeyadoss

### DIFFICULTY:

Easy

### PREREQUISITES:

Simple Math

### EXPLANATION:

Length wise, we could have produced a maximum of floor(N/K) squares and width wise, we could have produced a maximum of floor(M/K) squares. Multiply these two for the answer.

(N*M)/(K*K) might seem like a solution, but consider this : N=5,M=7,K=4. (7 * 5)/(4 * 4) is 2, but we can only produce one square from this rectangle(You can work it out by paper on why that’s the case!)
