Determine the base of a parallelogram with height 6 5/8 and area 26 1/2

jek_recluse [69]

The area of a parallelogram is found using the equation:

$a = b \times h$

where a is the area, b is the base, and h is the height. Substitute the known values into the equation.

$26 \frac{1}{2} = b \times 6 \frac{5}{8}$

Solve for b.

$26.5 \div 6.625 = b$

$b = 4$

The base of the parallelogram is equal to 4.

I don't know if this is the right answer though lol
