Answer: 
Step-by-step explanation:
To solve the exercise you must solve for b from the formula for the hypotenuse, as you can see below:
- Square both sides of the equation as following:

- Now you must subtract a² from each side of the equation, then you obtain:


- Apply square root to both sides:

Then:

Answer:
All of the above
Step-by-step explanation:
ALL of the above quadrilaterals have all these characteristics.

Answer: 819.73 yd²
<u>Step-by-step explanation:</u>

= 
= 
= 29 * 30
= 870

= π(4)²
= 16π
≈ 50.27
Area of the park = 
= 870 - 50.27
= 819.73
