What is the area of the parallelogram?
Slant Height = 21 cm
Height = 15 cm
Base = 20 cm
Answer:
300cm²
Step-by-step explanation:
The formula for the area of the parallelogram = Base × Height
Base = 20cm
Height = 15cm
Area = Base × Height
= 20cm × 15cm
= 300 cm²
Therefore, the area of the parallelogram is 300 cm²
