Question

यदि एक बंदूक 9 मिनट में 7 गोलियां छोड़ती है तो 1 घंटे में कितनी गोलियां छोड़ेगी​

Answer 1

Step-by-step explanation:

$\huge{\underline{\underline{Given→}}}$

$\sf\green{Length\:of\:rectangel=x+2\:units}$

$\sf\green{Breadth\:of\:rectangel=2x\:units}$

$\huge{\underline{\underline{To\:Find→}}}$

$\sf\purple{Perimeter\:of\:the\:rectangle}$

$\sf\color{purple}{Area\:of\:the\:rectangle}$

$\huge{\underline{\underline{Answer→}}}$

Perimeter:-

As perimeter =2(Lenght+Breadth)

$\sf\blue{→P=2(l+b)}$

$\sf\blue{→P=2(2x+x+2)}$

$\sf\blue{→P=4x+2x+4}$

$\sf\blue{→P=6x+4}$

$\mathrm{\boxed{\boxed{\pink{→P=6x+4✔}}}}$

Area:-

As area =Length x Breadth

$\sf\color{blue}{→Ar=l\times b}$

$\sf\color{blue}{→Ar=2x\times (x+2)}$

$\sf\color{blue}{→Ar=2x(x+2)}$

$\sf\color{blue}{→Ar=2x^2+4x}$

${\boxed{\boxed{\pink{→Ar=2x^2+4x✔}}}}$

☞ Hence the Perimeter of the rectangle is 6x+4 units and it's area is$\mathrm{2x^2+4x}2x </p><p> +4x units which is the required answer.$

HOPE IT HELPS.
