D, because 12/12-4/12=8/12.And since 8 and 12 can be simplified we simplify. 8÷4=2 and 12÷2=6. But it could be simplified again by 2. 2÷2=1 and 6÷2=3. Which leaves you with 1/3

A square has a perimeter of 8 cm. What is its area?
serious [3.7K]
A square has four sides which all have the same length.

So if we call the length of each side of the square 'a'

The sum of length of all the sides (the perimeter) will be ,

a + a + a + a = 4a

Now let's equal this to the perimeter to find the length of each side 'a'

4a\quad =\quad 8\\ \\ a\quad =\quad \frac { 8 }{ 4 } \\ \\ a\quad =\quad 2

So the length of each side of the square is 2 cm

To find area of a square we multiply the length of its two sides

So,

a\cdot a is the area of the square,

a\cdot a=\quad 2\cdot 2\quad =\quad 4\\ \\ 4\quad c{ m }^{ 2 }

The answer :

\boxed { 4\quad c{ m }^{ 2 } }

How much force does the atmosphere exert on one side of a vertical wall 4. 00-m high and 10. 0-m long?
serious [3.7K]

A force of 4.05×10⁶ N was exerted on one side of the wall.

<h3>What is the force?</h3>

Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.

The following data were obtained from the question:

Breadth (B) = 4 m

Length (L) = 10 m

Standard pressure (P) = 101325 Nm¯²

Next, we shall determine the area of the wall. This can be obtained as follow:

Area (A) = length (L) × breadth (B)

A = 10 × 4

A = 40 m²

Finally, we shall determine the force exerted on one side of the wall as follow:

Standard pressure (P) = 101325 Nm¯²

Area (A) = 40 m²

Pressure (P) = Force (F) /Area (A)

101325 = F/40

F = 101325 × 40

F = 4.05×10⁶ N.

Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.
