Answer:

Explanation:
step 1
Find the length side MU (height of triangle DUO)
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
Triangle DMU is similar to Triangle DPA by AA Similarity Theorem
because
∠DMU=∠DPA
∠MDU=∠PDA
Applying proportion

substitute the given values

solve for MU


step 2
Find the area of triangle DUO

substitute
