The area of the shaded region can be calculated by subtracting the combined area of the six circles from the area of the rectangle.
Area of rectangle = length x width = 0.8 cm x 1.2 cm = 0.96 square cm
Each circle has a radius of 0.4 cm (half the side length of the rectangle) and area = πr^2 = π(0.4)^2 = 0.16π square cm
Combined area of six circles = 6 x 0.16Ï€ = 0.96Ï€ square cm
Area of shaded region = Area of rectangle - Combined area of six circles
= 0.96 - 0.96π ≈ 0.83 square cm
Therefore, the answer closest to the area of the shaded region in the rectangle is:
0.83 square meters.
