${ \textbf{ \textsf{ \underline{ \underline{✠Question}}}}} :$

• Find the perimeter of the given figure

${ \textbf{ \textsf{ \underline{ \underline{✠Answer}}}}} :$

• The required perimeter is 42cm

${ \textbf{ \textsf{ \underline{ \underline{✠Basic \: terms}}}}} :$

• Rectangle :- A four side plane figure
• The opposite lines of rectangle are parallel
• Every angle of rectangle are 90°

• Square :- A square has all sides equal and every angle is equal to 90°

• Area of rectangle = l ×b

${ \textbf{ \textsf{ \underline{ \underline{✠Given \: That}}}}} :$

• Length of the given figure is 14cm
• Breath of the given figure is 7cm

${ \textbf{ \textsf{ \underline{ \underline{✠To \: Find}}}}} :$

• Perimeter of the given figure?

${ \textbf{ \textsf{ \underline{ \underline{✠Solution}}}}} :$

• As we asked to find the perimeter of the given figure of length is 14cm and breath is 7cm.
• As we can identify the given figure is a rectangle
• By using required formula, we may find the required perimeter of the rectangle.

${ \textbf{ \textsf{ \underline{ \underline{✠Caculation}}}}} :$

${ \underline{ \fbox{ \rm{Perimeter of \: Rectangle= 2×(l + b)}}}}$

• = 2×(14cm + 7cm)
• = 2× 21cm
• = 42cm

${ \underline{ \fbox{ \rm{Perimeter = 42cm}}}}$
