The height of a parallelogram is 3 times the base. the base measures 4.5cm. what is the area of the parallelogram?

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.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

the diameter is 16 cm. are you a teacher?
