Question

the perimeter of a rectangular field is 360cm and it's breadth is 75cm find its length​

Answer 1

Answer:

$perimeter \: of \: a \: rectangular \: field = 2(l + b) \\ \\ 360 = 2l + 2 \times 75 \\ \\ 360 = 2l + 150 \\ \\ 360 - 150 = 2l \\ \\ 210 = 2l \\ \\ l = \frac{210}{2} \\ \\ l = 105cm$

hope it is helpful

Answer 2

${\large{\bf{\red{\clubs{\underline{Given :}}}}}}$

The perimeter of a rectangle is 360cm and its breadth is 75cm.

${\large{\bf{\blue{{\clubs{\underline{To Find :}}}}}}}</p><p>$

Find the breadth of the rectangle.

￣￣￣￣￣￣￣￣￣￣￣￣

${\large{\bf{\green{{\clubs{\underline{Formula \: used :}}}}}}}$

${\sf{\pink{Perimeter \: of \: rectangle = 2(L+B)}}}$

Where,

${\sf{\purple{L = Length}}}$

${\sf{\purple{B = Breadth }}}$

￣￣￣￣￣￣￣￣￣￣￣￣

${\large{\bf{\orange{\clubs{\underline{Solution :}}}}}}$

Let B be x :

${\sf{\green{Length = 75cm}}}$

${\sf{\green{Breadth = x}}}$

${\sf{\blue{360cm = 2(75 + X) }}}$

${\sf{\blue{360cm = 150cm + 2x}}}$

${\sf{\blue{360cm - 150cm = 2x}}}$

${\sf{\blue{210cm = 2x}}}$

${\bf{\red{\boxed{X = {\cancel \frac{210}{2} = 105}}}}}$

${\mathfrak{\orange{\large{ \: \: \: \: \: \: \: Which \: is \: the \: required }}}}$

${\mathfrak{\orange{\large{ \: \: \: \: \: \: \: \: \: \: \: \: \: Answer }}}}$

Hence,

${\mathfrak{\blue{Length \: of \: the \: rectangle \: is \: 105cm .}}}</u></p><p><u>[tex]{\mathfrak{\blue{Length \: of \: the \: rectangle \: is \: 105cm .}}}$
