Question

The area of a parallelogram is 36 cm 2. The height of the parallelogram is 3 centimeters. How long is the base?

Answer 1

The answer is: " 12 cm " .
___________________________
Step-by-step explanation:
__________________________________
Formula for the area of a parallelogram:

Area = (base length) * (height) ; OR:
__________________________________
A = b * h ; Solve for "b" (base length):
__________________________________
Let us isolate "b" on one side of the equation:
_____________________________________
We have:
_____________________________________
A = b * h ;
_____________________________________
Divide EACH SIDE of the equation by "h" ; to isolate "b" on one side of the equation ;
______________________________________
A / h = (b * h) / h ;

to get: A / h = b ;

or: ↔ b = A / h ; Solve for "b" ;
______________________________________
We are given: "A = 36 cm² " ; "h = 3 cm" ;

So, we plug these values into the equation ;
______________________________________
b = (36 cm²) / (3 cm) = 12 cm .
______________________________________
The answer is: 12 cm.
__________________________________________
The base length of the parallelogram is: " 12 cm " .

Answer 2

Parallelogram Area = Height * Base
Base = Parallelogram Area / Height
Base = 36 / 3
Base = 12 centimeters
