In Exercises 47 to 50, use the fact that the area of the polygon is unique.In ▱ M N P Q ,   Q P = 12 and Q M = 9. The length of altitude Q R ¯ (to side M N ¯ ) is 6. Find the length of a altitude Q S ¯ from Q to P N ¯ . To determine

To find:

The length of the altitudes

Explanation

Converting theoretical statement into mathematical statement, identifying the geometric figure and the calculation is done by suitable geometric formulae.

Calculation:

Given,

Here, MN=b=12

QR=h=6
