Question

5. The area of a rectangle is 84 square cm. If its length is 63/8
cm, find its breath.

​

Answer 1

Answer:

10.66

Step-by-step explanation:

let the breadth= b

area of rectangle= l*b

84 = 63/8*b

84*8/63 = b

10.66= b

Answer 2

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\tt The \:area\: of\: a \:rectangle\: is \:84\:{cm}^{2} . If\: its\\\tt length\: is \dfrac{63}{8} \:cm, \:Find\: its \:breath.$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf {\boxed {\mathbb {GIVEN}}}$

• $\sf \bf Area \:of \:rectangle(A) =84\:{cm}^{2}$
• $\sf \bf Length\:of \:rectangle(l) =\dfrac{63}{8}\:cm$

$\sf \bf {\boxed {\mathbb {TO\:FIND}}}$

• $\sf \bf Breadth \:of \:rectangle(b)$

$\sf \bf {\boxed {\mathbb {SOLUTION}}}$

${\color {springgreen} \underline {\sf (i) Breadth\:of \:rectangle}}$

${\boxed {\boxed {\boxed {\color {blue} {\sf \bf A=l \times b}}}}}$

• $\sf A=area\:of \:the \:rectangle$
• $\sf l=length \:of \:the \:rectangle$
• $\sf b=breadth\:of \:the \:rectangle$

${\underbrace {\overbrace {\color {orange} {\bf Substitute \:the \:values}}}}$

$\sf \bf \implies 84=\dfrac{63}{8} \times b$

$\sf \bf \implies 84 \times 8 = 63\times b$

$\sf \bf \implies 672 = 63b$

$\sf \bf \implies b=\dfrac{672}{63}$

$\implies{\boxed {\boxed {\color {aqua} {\sf \bf b=10.67\:cm}}}}$

${\underbrace {\color {red} {\underline {\color {red} {\overline {\color {red} {\sf \therefore The \:breath \:of \:the \:rectangle \:is \:10.67\:cm}}}}}}}$

__________________________________________

$\sf \bf \huge {\boxed {\mathbb {EXTRA\:INFORMATION}}}$

$\bf Area\:of \:rectangle = l \times b$

$\bf Perimeter\:of \:rectangle = 2 \Big(l + b\Big)$

$\bf Diagonal\:of \:rectangle = \sqrt{{b}^{2}+{l}^{2}}$
