We Know the Formula For Pressure
\boxed{ \bf{Pressure = \dfrac{Force}{Area} }}
Pressure=
Area
Force
Where, Pressure is in Pascal.
Force is in Newton.
Area is in metre square.
⠀
We Have to Change Area into Meter Square.
⇒ Area = 4 cm²
⇒ Area = 4 / 100 × 100
⇒ Area = 4 / 10,000 m²
⠀
\longrightarrow \bf{P = \dfrac{F}{A} }⟶P=
A
F
\longrightarrow \bf{P = \dfrac{20}{ \frac{4}{10000} } }⟶P=
10000

20
\longrightarrow \bf{P = \dfrac{( \cancel20 \times 10000)}{ \cancel4} }⟶P=
4
(

0×10000)
\longrightarrow \bf{P = 5 \times 10000}⟶P=5×10000
\longrightarrow \bf{P = 5 \times {10}^{4} \: Pascal}⟶P=5×10

Pascal
⠀
\therefore∴ Pressure will be 5×10⁴ Pascal.
