I say 12 because that would mean the first rectangle is 6x12 and the second is 10x12
A² + b² = c²
a² = c² - b²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = √45
a ≈ 6.7082
a = 6.7
Answer:7
Step-by-step explanation:
Hope this helps
0.8 or 4/5
Both are correct, but in different form.
Your welcome.
Area = (side length)^2
Here,
64n^36 = s^2. Take the sqrt of both sides, obtaining 8n^18 = s. This is the principal square root. We use this positive quantity because the measure of side length must be positive.
