Answer 2

${\underline {\underline {\huge {\sf { Required \: Answer: } }}}}$

11.$\boxed { \sf \pink { Side = 40m }}$

12.$\boxed { \sf \pink {length= 25m }}$

(Solution 11.)

Given:

• Area of a square plot = 1600 m²

To calculate:

• Side of the plot

Calculation:

We know that,

• ${\underline {\boxed {\Large {\sf { Ar. \: of \: sq. = {(Side)}^{2} } }}}}$

$\sf { ⇢ 1600 = {(Side)}^{2} }$

$\sf { ⇢ Side = \sqrt{1600} }$

$\boxed { \sf \pink { ⇢ Side = 40m }}$

Side of the plot is 40m.

(Solution 12.)

Given:

• Area of rectangular field = 250 m²

• Breadth of the field = 10 m

To calculate:

• length

Calculation:

We know that,

• ${\underline {\boxed {\Large {\sf { Ar. \: of \: rec. = l \times b} }}}}$

$\sf { ⇢ 250 = l \times 10}$

$\sf { ⇢ 250 = 10l }$

$\sf { ⇢ l = \dfrac{250}{10} }$

$\boxed { \sf \pink { ⇢ l = 25m }}$

Therefore, length of the field is 25m.
