Find the area.<br> help pls
lions [1.4K]

Answer:

81.6 inches squared

Step-by-step explanation:

The formula for calculating all parallelograms is Area+=base*height.

The height is given to you, 6.8, the base of the figure is also given, 12.

Now all you have to do is to multiply.

That would get you to 81.6.

(When asked for area of parallelogram, the length of any line other than the height and base is not needed)

Whitepunk [10]
To answer the given above, multiply the whole equation with least common multiple of the denominators which is 5n. Shown below, 
 
                                           (4/5n - 1/5 = 2/5n) x 5n
