Question

find the length of a rectangular garden whose area is 216 square meter and breadth 12 m​

Answer 1

Answer:

area of a rectangle = l× b

216 m² = l× 12m

216m² / 12 m = l

16 m = l

therefore the length of the rectangular garden is 16 m

Answer 2

•Question:-

• Find the length of a rectangular garden whose area is 216 square meter and breadth 12 m.

Given:-

• Area of rectangle is 216 m²
• Breadth of rectangle is 12m

To find:-

• Length of rectangle

$\huge{ \sf{ \underline{ \overline{ \mid{ \color{maroon}{Solution:- } \mid}}}}}$

• Let the length be l

⇝Area of rectangle = length ×breadth

⇝ L×12 m = 216m²

$\bf \: ⇝ \sf{l} \: = \frac{216}{12} m$

⇝l= 18m

$\large{ \boxed{ \mathfrak{ \green{ \underline{Therefore \: the \: measure \: of \: length \: is \: 18m}}}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \huge{ \sf{ \underline{ \purple{Verification:- }}}}$

• By keeping the value of length we will check our answer

$area \: = \: length \times breadth$

$⇝18 \: m \times 12 \: m$

$⇝216 {m}^{2}$

Hence Proved✔
