Final answer:
To find the height of the rectangle with a known base of 39 cm and area of 245 cm², use the formula for the area of a rectangle (Area = base × height), which gives an approximate height of 6 cm.
Step-by-step explanation:
If the base of a rectangle is 39 cm and the area is 245 square centimeters, we need to find the height of the rectangle. The area of a rectangle is calculated using the formula Area = base × height. In this case, we know the Area (245 cm²) and the base (39 cm), so we can rearrange the formula to solve for the height:
Height = Area / Base
Height = 245 cm² / 39 cm = 6.28205 cm. When rounded to the nearest whole number, the height of the rectangle is approximately 6 cm which is option A.
