Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
Equilateral triangle is a triangle with the 3 sides of the same length, and the 3 angles with the same measures/degree.
The formula to find the area of a triangle is base x height/2 , you do have the base (40), but you need the height. To find the height of an equilateral triangle you use the formula: side/2 x radical3, this way u'll find the height and therefor can calculate the area of the triangle.
Hope that helped :)
Respuesta:
30,6 metros
Explicación paso a paso:
Dado :
Presión = 300 Kpa
Usando la fórmula que relaciona la presión y la profundidad:
Presión = profundidad * aceleración debida a la gravedad * densidad del agua
Densidad del agua = 1000 kg / m³
Presión = 300Kpa = 300 * 10 ^ 3 Pa
300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000
300000 = profundidad * 9800
Profundidad = 300000/9800
Profundidad = 30,612
Profundidad = 30,6 m
