Question

If the perimeter of a rectangle is 48 cm and ites breabreadth is 10 cm find the length of the rectangle

Answer 1

$\sf{\bold{\green{\underline{\underline{Given}}}}}$

• Perimeter = 48cm
• breadth = 10cm

______________________

$\sf{\bold{\green{\underline{\underline{To\:Find}}}}}$

• length = ??

______________________

$\sf{\bold{\green{\underline{\underline{Solution}}}}}$

$\sf{\red{\boxed{\bold{perimeter\: of\: rectangle = 2( length + breadth)}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ 48 = 2 ( length + 10cm)}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ length + 10cm = \dfrac{48}{2}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{length + 10cm = 24}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Length = 24 - 10}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Length = 14cm}}$

$\sf{\bold{\green{\underline{\underline{Answer}}}}}$

• Length of the rectangle = 14cm

⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

$\sf{\orange{\boxed{\bold{Let's\: Explore}}}}$

⠀⠀⠀⠀

• Perimeter of triangle = a + b + c
• Perimeter of rectangle = 2 ( l + b )
• Perimeter of square = 4 × side
• Perimeter of circle = 2× pi × R
• Perimeter of irregular object = sum of all sides

Answer 2

Answer :-

• Length of rectangle = 14cm

⠀⠀⠀⠀

Step by Step Explanation :-

⠀⠀

GivEn :-

⠀⠀⠀⠀

• Perimeter of rectangle = 48cm
• Breadth of rectangle = 10cm

⠀⠀⠀⠀

To Find :-

⠀⠀⠀⠀

• Length of rectangle = ??

⠀⠀⠀⠀

Solution :-

⠀⠀⠀⠀

We all know that ;

perimeter of rectangle = 2 ( l + b )

⠀⠀⠀⠀

• Putting given values in the formulae

⠀⠀⠀⠀

48 = 2 ( length + 10 )

⠀⠀⠀⠀

length + 10 =48 / 2

⠀⠀

length + 10 = 24

⠀⠀⠀⠀

length = 24 - 10

⠀⠀

length = 14cm
