Question

The perimeter of a rectangular sheet is 300cm. If the

breadth of this sheet is 60cm,find the length​

Answer 1

Answer:

$given \: perimeter \: s = 300 \: cm \\ \: bredth \: b \: = 60cm \: \\ length \: = l = to \: find \: \\ so \: perimeter \: s = 2 \times (l + b) \\ \\ l = \frac{s}{2} - b \\ \\ = \frac{300}{2} - 60 \\ \\ = 90 \: cm \:$

So lenght = 90cm

Answer 2

A N S W E R :

• The Length is 90 cm

Given :

• The perimeter of a reactangle sheet is 300 cm

To find :

• Find the Length ?

$\large\star$ As we know that,

$\large\dag$ Formula Used :

• $\boxed{\bf{Perimeter\:=\:2\:\times\; \bigg(Length\:+\; Breadth\bigg)}}$

Solution :

:$\implies$${\sf{Length\:=\; \dfrac{Sheet}{2} \:-\:B}}$

$~~~~~$:$\implies$${\sf{Length\:=\; \dfrac{300}{2} }}$

$~~~~~~~~~~$:$\implies$${\sf{Length \:=\; {\cancel{\dfrac{300}{2}}}}}$

$~~~~~~~~~~~~~~~~$:$\implies$${\underline{\boxed{\frak{\pink{90\:cm}}}}}$★

Hence,

• ${\underline{\textsf{The\; \textbf{Length}\:is\; \textbf{90\:cm}.}}}$

$~~~~$$\qquad\quad\therefore{\underline{\textsf{\textbf{Hence, Verified!}}}}$
