Answer:
Height = 13.86 cm
Step-by-step explanation:
1. Find the length of each side
48/3 = 16
2. cut the triangle in half.
Base = 8 Hypotenuse = 16
3. use the formula A^2 + B^2 = C^2
(16^2 - 8^2)^(1/2) = 13.86 cm
Answer: Yes, it will be enough.
Step-by-step explanation:
I will answer this in English:
We have 27 students and 81 units, we want to give 3 units to each student.
This is only possible if the quotient betwen 81 and 3 must be bigger than 27.
Lets do it:
81/3 = 27
So we have exactly enough for the 27 students.
Answer:
Confusing but I got the width is either 12 or 20
12 × 20 = 240 = area check
64 = perimeter = 12 + 12 + 20 + 20 = check
it does not give specifics on what is length so it's one of the 2 which ever one is the width the other is length
