Final answer:
The area of a rectangle with length 3x^(2)y units and breadth 5x^(2) units is 15x^(4)y square units.
Step-by-step explanation:
In mathematics, the area of a rectangle is calculated by multiplying its length and breadth. Given that the length, l, is 3x^(2)y units and the breadth, b, is 5x^(2) units, we can substitute these values into the formula for the area of a rectangle, which is A = l*b.
By substituting these values, we find that the area, A, equals 3x^(2)y * 5x^(2), which simplifies to 15x^(4)y square units.
