Final answer:
The area of the parallelogram with a base of 3 1/2 cm and a height of 1 2/7 cm is 4.5 cm^2.
Step-by-step explanation:
The area of a parallelogram can be found by multiplying the base by the height. Given that the base of the parallelogram is 3 1/2 cm (which is the same as 3.5 cm when converted to decimals) and the height is 1 2/7 cm (which is approximately 1.2857 cm when converted to decimals), we can calculate the area.
To find the area of the parallelogram, we use the formula:
Area = Base × Height
So,
Area = 3.5 cm × 1.2857 cm
Area = 4.5 cm^2 (rounded to one decimal place)
Thus, the area of the parallelogram is 4.5 cm^2.
