In Double integration, the interval [a, b] should be divided into [c, d) should be divided into --sub intervals of size k. --subintervals of size h and the interval
Answer
equal, equal
equal, unequal
unequal, equal
unequal, unequal

In double integration, the interval [a, b]  is typically divided into equal subintervals of size k, and the interval [c, d]  is divided into equal subintervals of size h.

So, the correct answer is equal, equal.

This means both intervals are subdivided into equal lengths, making it easier to apply numerical methods like the rectangle method, trapezoidal rule, or Simpson’s rule in double integration.
