Question

the length of a rectangle is 4 metre and breadth is 300 cm find its perimeter and area​

Answer 1

Question:-

• The length of a rectangle is 4 meter and breadth is 300 cm. Find its perimeter and area.

Given :-

• Length of Rectangle = 4 meter

• Breadth of Rectangle = 300 cm

To Find :-

• Area of Rectangle

• Perimeter of Rectangle.

Solution :-

Let the length of Rectangle is 'l' and breadth of Rectangle is 'b' so ,

$\star \sf \: l = 4 \: m$

$\star \sf \: b = 300cm \\ \\ \sf \: \mapsto \: b= \frac{300}{100} \: m \\ \\ \mapsto \sf \: b = 3 \: m$

We know that :-

• $\sf \: perimeter \: of \: rectangle = 2(l + w)$

so,

$\star \sf \: perimeter \: of \: rectangle = 2(4 + 3) \\ \\ = \sf \: 2 \times 7 \\ \\ \boxed{ \star \sf \: perimeter \: of \: rectangle = 14 \: m}$

Now, we know that :-

• $\sf \: area \: of \: rectangle = l \times b$

so,

$\star \sf \: area \: of \: rectangle = 4 \times 3 \\ \\ = \sf \: 12 \\ \\ \boxed{ \star \sf \: area \: of \: rectangle = 12 \: {m}^{2} }$

Answer 2

$Question:-$

The length of a rectangle is 4 meter and breadth is 300 cm. Find its perimeter and area.

$given$

Length of Rectangle = 4 meter

Length of Rectangle = 4 meterBreadth of Rectangle = 300 cm

$to \: find$

Area of Rectangle

Area of RectanglePerimeter of Rectangle.

$Solution :-$

Let the length of Rectangle is 'l' and breadth of Rectangle is 'b' so ,

$\star \sf \: l = 4 \: m⋆l=4m$

$\begin{gathered} \star \sf \: b = 300cm \\ \\ \sf \: \mapsto \: b= \frac{300}{100} \: m \\ \\ \mapsto \sf \: b = 3 \: m\end{gathered}$

We know that :-

$\sf \: perimeter \: of \: rectangle = 2(l + w)perimeterofrectangle=2(l+w)$

so,

$\begin{gathered} \star \sf \: perimeter \: of \: rectangle = 2(4 + 3) \\ \\ = \sf \: 2 \times 7 \\ \\ \boxed{ \star \sf \: perimeter \: of \: rectangle = 14 \: m}\end{gathered}$

Now, we know that :-

$\sf \: area \: of \: rectangle = l \times b \:$

so,

$\begin{gathered} \star \sf \: area \: of \: rectangle = 4 \times 3 \\ \\ = \sf \: 12 \\ \\ \boxed{ \star \sf \: area \: of \: rectangle = 12 \: {m}^{2} }\end{gathered}$
