Answer:
60.75
Step-by-step explanation:
Use the formula for area of a parallelogram; Base times Height.
Put 4.5 in the formula for base, because it is the base. The formula is now 4.5 times Height.
If the base measures 4.5, and the height is three times that, then multiply 3 by 4.5. This gives you the answer 13.5.
Now put in 13.5 to the equation for height, this is because it is the height that we've now found. The formula is now 4.5 times 13.5.
4.5 times 13.5 is 60.75, so the area of the parallelogram is 60.75 centimeters squared.
