Answer:

B. 2800 sq mm

Step-by-step explanation:

Given the following data;

Length = 80 mm

Width = 70 mm

Area of rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

Area of rectangle = 80 * 70

Area of rectangle = 5600 mm²

Since the paper (area of rectangle) was halved, we would divide by 2;

Area of each half = 5600/2

Area of each half = 2800 sq mm.
