A

Step 1: Calculate the area of one square, which is given as 5.29 cm².
Step 2: To find the area of 7 squares, we multiply the area of one square by 7:
\( 5.29 \text{ cm}^2 \times 7 = 37.03 \text{ cm}^2 \)
Step 3: Consider significant figures. The area of one square (5.29 cm²) has three significant figures, so we need to round 37.03 cm² to three significant figures.
Step 4: Rounding 37.03 cm² to three significant figures gives us 37.0 cm².
Therefore, the area of 7 such squares, taking into account the significant figures, is 37.0 cm².
