$\given\ \\ area \: of \: rectangle \: = \: 437sq.cm \\ length = 38 \: cm \\ breadth = what \\ area \:of \: rectangle = l \: \times b \\ 437 \: = 38 \times b \\ 437 = 38b \\ \dfrac{437}{38} = b \\ so. \: \\ b = 11.5 \: cm$

$\large\begin{gathered} {\underline{\boxed{ \rm {\purple{Area \: \: of \: \: rectangle \: = \:L \: × \: B}}}}}\end{gathered}$

• L denotes length of rectangle.

• B denotes breadth of rectangle.

☛ Substuting the values

$\bf \large \rightarrow \: \: Area \: \: of \: \: rectangle \: = \:L \: × \: B$

$\bf \large \rightarrow \: \: 437 \: = \:38 \: × \: B$

$\bf \large \rightarrow \: \: \frac{437}{38} \: = \: B$

$\bf \large \rightarrow \: \: \cancel\frac{437}{38} \: \: ^{11.5} \: = \: B$

$\bf \large \rightarrow \: \: 11.5 \: = \: B$

Hence , the Breadth of rectangle is

11.5 cm.
