Question

perimeter of rectangle is cm. length is(2x-1) and breadth is (x+1) find the value of x
​

Answer 1

$\huge\rm\underline\pink{Given࿐}$

$\large\fbox\red{ length = (2x-1)}$

$\large\fbox\green{breath = (x+1)}$

$\huge\fbox\blue{ perimeter = 62 cm}$

$\huge\rm\underline\pink{To find࿐}$

$\huge\fbox\red{x = ?}$

$\huge\rm\underline\pink{Solution࿐}$

$\huge\rm\underline\red{we know that↯}$

$\huge\rm\underline\pink{perimeter = 2(l + b)}$

Also perimeter = 62 cm

so,

$2(l+b) = 62 \\ \\ ↬ (l+b) = 31 \\ \\ ↬ (2x-1) + (x+1) = 31 \\ \\ ↬ 2x -1 + x + 1 = 31 \\ \\ 3x = 31 \\ x = \frac{31}{3}$
