The lengths of the shorter altitude and the shorter side of parallelogram are 9cm and root 82 cm, respectively. the length of a longer diagonal is 15 cm. what is the area of this parallelogram

Consider parallelogram ABCD. The shorter sides are AB and CD, so cm.

The shorter altitudes are BH=CF=9 cm.

1. Consider right triangle FCD:

2. Consider right triangle FCA:

3.

4. Therefore, the area of parallelogram ABCD is

sq. cm.

99 sq. cm.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
