Answer:
Area of the parallelogram = 21.6 cm²
Step-by-step explanation:
Area of a parallelogram = Base × Height of the side parallel to the base
By using ruler,
Base = 4.8 cm
Height of parallelogram = 4.5 cm
Area of the parallelogram = 4.8 × 4.5
= 21.6 cm²
.725 multiplied by 4500=362.5
750+3262.5=4012.5
0.08 if 4 divided by 50
12.5 if 50 divided by 4
Answer:

Step-by-step explanation:
