Base = Height, Let them be x.
![( x \times x) \div 2 = (x + x) + 6 \\ x ^{2} \div 2 = 2x + 6 \\ \frac{1}{2} x^{2} - 2x - 6 = 0](https://tex.z-dn.net/?f=%28%20x%20%5Ctimes%20x%29%20%5Cdiv%202%20%3D%20%28x%20%2B%20x%29%20%2B%206%20%5C%5C%20x%20%5E%7B2%7D%20%5Cdiv%202%20%3D%202x%20%2B%206%20%5C%5C%20%5Cfrac%7B1%7D%7B2%7D%20x%5E%7B2%7D%20-%202x%20-%206%20%3D%200)
Solve quadratic equation:
x=6, x=-2(rejected because base and height is positive)

Answer:
$750
Step-by-step explanation:
The 20% discount multiplies the price by (1 - 20%) = 0.80.
The 15% discount multiplies the price by (1 - 15%) = 0.85.
After applying the discounts to the initial price P, we have ...
P(0.80)(0.85) = $510
P = $510/(0.80·0.85) = $750
The price before discounts was $750.
