How to get the perimeter of the triangle?</h3>
We can see a right triangle, by using the Pythagorean theorem we can get the missing cathetus:
Now we know the measure of the 3 sides, then the perimeter of the given triangle is:
P = 15cm + 20cm + 25cm = 60cm
The perimeter of the triangle is 60cm.

Answer:
volume = 36 cm³
Step-by-step explanation:
The volume of a rectangular prism = lwh
where
w = width
l = length
h = height
The base of a rectangular prism is a rectangle and the area of a rectangle is the product of length and width. Therefore,
base area of the rectangular prism = length × width
base area = lw
Base area of the rectangular prism = 12 cm²
Recall, the formula of the volume of a rectangular prism is the product of the length, width and height.
volume = lwh
substitute lw value in the formula above
volume = 12 × 3
volume = 36 cm³
Answer:
m ≤ - 10
Step-by-step explanation:
m/-5 ≥ 2
Multiply both sides by -5 to isolate m. Because we are multiplying by a negative, we must flip the sign.
m ≤ -10
