Question

If the area of a rectangle is 60 cm and the length is 5cm and the width is (x+4) find x​

Answer 1

$\huge \text{Answer:}$

Answer 2

$\;\;\underline{\textbf{\textsf{ Given:-}}}$

•The area of the rectangle is 60 cm

• Length of the rectangle is 5 cm

• Width of the rectangle is (x + 4) cm.

$\;\;\underline{\textbf{\textsf{ To Find :-}}}$

•Value of x

$\;\;\underline{\textbf{\textsf{ Formula Used :-}}}$

$\bigstar{\underline{\boxed{\sf\green{Area\:of\: rectangle = Length \times Breadth}}}}$

$\;\;\underline{\textbf{\textsf{ Solution :-}}}$

We know that,

$\bigstar{\underline{\boxed{\sf\green{Area\:of\: rectangle = Length \times Breadth}}}}$

$\:\:\:\:\dag\bf{\underline \green{Put\:the\:given \:values:-}}$

$\longrightarrow \sf {60 = 5 \times (x + 4)}$

$\longrightarrow \sf {60 = 5x + 20}$

$\longrightarrow \sf {5x = 40}$

$\longrightarrow\sf \:x = \cancel{\dfrac{40}{5} }$

$\longrightarrow\large{\sf{\green{x = 8}}}$

$\:\:\:\:\dag\bf{\underline{\underline \green{Hence:-}}}$

• The required value of x is 8.
