Question

Find the breadth of a rectangle whose area is 285 sq.cm and length is 19cm.​

Answer 1

Answer:

b = 15cm

Step-by-step explanation:

Area of rectangle = 285cm²

Length of rectangle = 19cm

Breadth of rectangle = ?

Now,

Area of rectangle = l × b

285 = 19 × b

b = 285/19

b = 15cm

Answer 2

Answer:

Area of Rectangle = 285 cm²

Length (L) = 15 cm

★ \large {\boxed{\sf{Area \: = \: Length \: \times \: Breadth}}}

\implies {\sf{Breadth \: = \: \dfrac{Area}{Length}}}

\implies {\sf{Breadth \: = \: \dfrac{\cancel{285}}{\cancel{15}}}}

\implies {\sf{Breadth \: = \: 19 \: cm}}

∴ Breadth is of 19 cm

\rule{200}{1}

\huge \boxed{ {{\sf{ \red{P}}} {\mathfrak{ \blue{r}}} {\rm{ \green{o}}} {\sf{ \orange{o}}} \tt{f}}}

Put Values in formula :

★ \large {\boxed{\sf{Area \: = \: Length \: \times \: breadth}}}

\implies {\sf{285 \: = \: 19 \: \times \: 15}}

\implies {\sf{285 \: = \: 285}}

Hence Proved
