Question

• The length of rectangle is 5.8 cm and breadth is 3.5 cm. Then what is the area and perimeter of rectangle?

Answer

• Perimeter = 18.6cm
• Area = 20.3 cm²

Given

• Length of rectangle = 5.8cm
• Breadth = 3.5

To Calculate ji8

• Area & Perimeter __?

Step by Step Explanation

Length of rectangle = 5.8cm ( Given )

Breadth of rectangle = 3.5 cm ( Given )

☆ Area of rectangle = Length × Breadth

➺ 5.8×3.5

➺ 20.3

Area = 20.3 cm²

☆ Perimeter = Sum of all sides

➺ 2(5.8+3.5)

➺ 2×9.3

➺ 18.6

Perimeter = 18.6cm

$\bf\underline{\underline{\green{SOLUTION:-}}}$

• Perimeter = 18.6cm
• Area = 20.3 cm²

Answer 2

$\;\;\underline{\textbf{\textsf{ Given :-}}}$

• Length of rectangle is = 5.8cm

• Breadth is = 3.5 cm

$\;\;\underline{\textbf{\textsf{ To Find:-}}}$

• Area of the rectangle

• Perimeter of the rectangle

$\;\;\underline{\textbf{\textsf{ Solution :-}}}$

$\underline{\:\textsf{ As we know that :}}$

$\star\;{\boxed{\sf{\purple{Area_{\;(Rectangle)} = Length × Breadth)}}}}$

$\underline{\:\textsf{ Now, put the given values :}}$

$\dashrightarrow \sf Area = 5.8× 3.5$

$\dashrightarrow \sf Area = 20.3$

$\dashrightarrow {\boxed{\frak{\purple{Area= 20.3cm²}}}}\;$

ㅤ$\;\;\underline{\textbf{\textsf{ Therefore -}}}$

$\underline{\textsf{Area of the given rectangle is \textbf{ 20.3cm²}}}.$

Again, we are asked to find the perimeter of the given rectangle.

$\underline{\:\textsf{We know that :}}$

$\star\;{\boxed{\sf{\purple{Perimeter_{\;(Rectangle)} = 2(l + b)}}}}$

$\sf Where,$

• l = Length

• b = Breadth

$\underline{\:\textsf{ Putting the given values :}}$

$\dashrightarrow \sf Perimeter =2(5.8+3.5)$

$\dashrightarrow \sf Perimeter =18.6cm$

$\dashrightarrow {\boxed{\frak{\purple{Perimeter = 18.6cm }}}}\;$

ㅤ$\;\;\underline{\textbf{\textsf{ Hence-}}}$

$\underline{\textsf{Perimeter of the given rectangle is \textbf{ 18.6cm }}}.$
