Question

$The \: area \: of \: ​​a \: rectangular \: plot \: is \: 440 {m}^{2} , \: if \: its \: length \: is \: 22m, \: then \: what \: will \: be \: its \: perimeter?$
$( \: a \: ) \: 20m$
$( \: b \: ) \: 42m$
$( \: c \: ) \: 64m$
$( \: d \: ) \: 84m$
solve this Question ⬆️⬆️⬆️​

Answer 1

Answer:

$(d) \: 84 m$

Step-by-step explanation:

$Given, \: l \times b = 440\: {m^2} \: and \: l= 22$

$\therefore b=\frac{440}{22}=20\: m$

$Perimeter = 2(l+b)$

$=2(22+20)=84\: m$

Answer 2

Answer :-

• Breadth = 20m
• Perimeter = 88m

Step by step explanation :-

Given that,

• Area of rectangle = 440m²
• Length = 22m

Need to find,

• Breadth
• Perimeter

Using formulas,

• Area of rectangle = l × b
• Perimeter = 2(l + b)

Taking area of rectangle formula,

→ 440 = 22 × b

→ b = 440/22

→ b = 20

Now, using perimeter formula,

→ Perimeter = 2(22 + 20)

→ Perimeter = 2(42)

→ Perimeter = 84m
