a parallelogram has an altitude of 19 cm and a base of 15 cm. What is its area?
area of ||gram = base x height
245
To find the area of a parallelogram, you need to know the length of its base and the length of its altitude (or height). The area of a parallelogram is calculated by multiplying the length of the base with the length of the altitude.
In this case, you know that the base of the parallelogram is 15 cm and the altitude is 19 cm. To find the area, you can use the following formula:
Area = base × altitude
Substituting the known values:
Area = 15 cm × 19 cm = 285 cm²
Therefore, the area of the parallelogram is 285 square centimeters.
