Answer:

14.21 units (14.2)

Step-by-step explanation:

Formula for area is W(L) or width multiplied by length.

The formula for finding the length of a rectangle's diagonal is :

d = \sqrt{w^{2}+l^{2}  }

Now we solve for d.

d = \sqrt{w^{2} + (\frac{A}{W})^{2}

= \sqrt{9^{2} + (\frac{99}{9})^{2}

≈ 14. 21267

≈ 14.2

One of the triangles is 2 x 2. Area of 2. Subtract 2 from 20.
20 - 2 = 18 
Another is 2 x 5. Area of 5. Subtract 5 from 18. 
18 - 5 = 13 
The last is 3 x 4. Area of 6. Subtract 6 from 13. 
13 - 6 = 7 
The area of the triangle QRS is A, 7.
