Question

Find the area of a square park whose perimeter is 320m.​

Answer 1

Given :

• Perimeter of the square park 320m.

$~$

To Find :

• The area of a square park ?

$~$

${\rule{190pt}{2pt}}$

SolutioN :

• Let us assume that, the unknown side of square be x.

$~$

${\bf{\dag}}$ Formula Used :

$~$

$\qquad\star~{\underline{\boxed{\pmb{\sf{Perimeter~=~4 side}}}}}$

$\qquad\star~{\underline{\boxed{\pmb{\sf{Area~=~side^2}}}}}$

$~$

${\bf{\dag}}$ According to the Question :

$~$

$\qquad{\sf:\implies{320~=~4~×~x}}$

$~$

$\qquad{\sf:\implies{x~=~\cancel\dfrac{320}{4}}}$

$~$

$\qquad:\implies{\pmb{\underline{\boxed{\purple{\frak{x~=~80 }}}}}}$★

$~$

Now,

$~$

$\qquad$ ∴ The side of the square is 80m.

$~$

Therefore,

$~$

$\qquad{\sf\dashrightarrow{Area~=~80^2}}$

$~$

$\qquad\dashrightarrow{\pmb{\underline{\boxed{\pink{\frak{Area~=~6400 }}}}}}$★

$~$

Hence,

$~$

$\qquad$ ∴ The area of a square park is 6400m.

Answer 2

Answer:

The rainforests are depleting because of the large scale development and industrial activities. Deforestation has increased, because of which the topsoil of land is getting washed away, decreasing the soil fertility. As a result, trees are unable to grow and the rainforests are depleting.
