Using the formula for the area of a rectangle with sides a and b, calculate the area of a rectangle at a = 2.5cm and b = 4cm.

From the conditions of the assignment given:

a = 2.5 cm.

b = 4 cm.

We need to find the S of the rectangle.

To find the area of a rectangle, multiply its length by width.

We get: S = a * b = 2.5 cm * 4 cm = 10 cm2.

Answer: The area of the rectangle is 10 cm2.
