Answer 1

Answer:

according to this question

5*x+4 = 60

x+4 = 60/5

x + 4 = 12

x = 12-4

x = 8

Answer 2

${\mathbf {\blue{S}{\underline{\underline{olution:-}}}}}$

$\mathfrak{\underline{AnswEr:-}}$

• The required value of x = 8

$\mathfrak{\underline{Given:-}}$

• The area of the rectangle is 60 cm and the length of the rectangle is 5 cm, and the width of the rectangle is (x + 4) cm.

$\mathfrak{\underline{Need\:To\: Find:-}}$

• Find the required value of x = ?

${\mathbf {\blue{E}{\underline{\underline{xplanation:-}}}}}$

$\:\:\:\:\dag\bf{\underline \green{Formula\:used\:here:-}}$

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

$\:\:\:\:\dag\bf{\underline \blue{Putting\:the\:values:-}}$

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

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

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

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

$\longrightarrow\large\boxed{\sf{\purple{x = 8}}}$

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

• The required value of x is 8.
