Final answer:
The area of the rectangle with a length of 7 cm and an estimated width of 1.25 cm is 8.75 cm².
Step-by-step explanation:
When calculating the area of a rectangle, the formula used is length × width. Given that the length of the rectangle is 7 cm and the width is estimated to be 1.25 cm based on the measurement between 1.2 and 1.3 cm marks, we can use these dimensions to find the area.
To calculate the area, multiply the length by the width:
Area = 7 cm × 1.25 cm = 8.75 cm².
The area of the rectangle is 8.75 square centimeters.
