Question

3. Find the breadth of a rectangular plot of land, if its area is 440 m2

and the length is

22 m. Also find its perimeter.
​

Answer 1

${\boxed{\boxed{\red{\mathbb{ANSWER:}}}}}$

• Breadth of plot = 20 m
• Perimeter of plot = 84 m

Given:

• Area of rectangular plot = 440 m²
• Length of plot = 22 m

To Find:

• Breadth of plot.
• Perimeter of plot.

${\boxed{\boxed{\red{\mathbb{SOLUTION:}}}}}$

Now, we know that,

$\implies$ Area of rectangular plot = l × b

$\implies$ 440 = 22 × b

$\implies$ b = 440/22

$\implies$ b = 20 m

Hence, breadth of plot = 20 m

Now, we will find perimeter of plot,

$\implies$ Perimeter of plot = 2(l + b)

$\implies$ Perimeter of plot = 2(22 + 20)

$\implies$ Perimeter of plot = 2(42)

$\implies$ Perimeter of plot = 84 m.

Hence, Perimeter of plot = 84 m.

Answer 2

$\sf \: required \: answer$

Breadth of plot = 20 m

Perimeter of plot = 84 m

$\sf \: given \:$

Area of rectangular plot = 440 m²

Length of plot = 22 m

$\sf \: to \: find$

Breadth of plot.

Perimeter of plot.

$\sf \: solution$

Now, we know that,

⟹ Area of rectangular plot = l × b

⟹ 440 = 22 × b

⟹ b = 440/22

⟹ b = 20 m

Hence, breadth of plot = 20 m

Now, we will find perimeter of plot,

⟹ Perimeter of plot = 2(l + b)

⟹ Perimeter of plot = 2(22 + 20)

⟹ Perimeter of plot = 2(42)

⟹ Perimeter of plot = 84 m.

Hence, Perimeter of plot = 84 m.
