10 x 10 = 100 80 x 80 =6400 6400-100= 6300 so that would have to be 3150ft.
Answer:
D. 4
Step-by-step explanation:

20% of 150 is 30
Change the percentage into a decimal by dividing it over 100:
20 / 100 = 0.2
Multiply:
0.2 × 150 = 30
It’s false!!! Hope this helped;)
The answer is 112 centimeters.
As this problem represents a right triangle, here we need to apply the Pythagorean Theorem.
- h = √113² - 15²
- h = √12769 - 225
- h = √12544
- h = 112 centimeters
