For a) the integral is ∫ dy ∫ dx 1 with the following limits:

The lower limit of the outer integral is 0

The upper limit of the outer integral is 4

The lower limit of the inner integral is y/2

The upper limit of the inner integral is sqrt(y)

For b) the integral is ∫ dx ∫ dy 1 with the following limits

The lower limit of the outer integral is 0

The upper limit of the outer integral is 2

The lower limit of the inner integral is x^{2}

The upper limit of the inner integral is 2x

Both integral evaluate to the same result which is 4/3
