Answer 1

Answer:

$\large\tt\color{red}\underline{\underline{Question:}}$

The length of the rectangle is 15 meters and its perimeter is 48 meters . Find the breadth .

$\large\tt\color{blue}\underline{\underline{Given:}}$

$Perimeter\:of\:the\:rectangle=48\:meters$

$Length\:of\:the\:rectangle=15\:meters$

$\large\tt\color{purple}\underline{\underline{To\:find:}}$

$Breadth\:of\:the\:rectangle=??$

$\large\tt\color{green}\underline{\underline{Taken:}}$

$Let\:the\:breadth\:be\:2x$

$2×(L+x)=48\:m$

$\large\tt\color{pink}\underline{\underline{Solution:}}$

$2×(15m+x)=48\:m$

$30m+2x=48\:m$

(Done cross multiplication)

$2x=48\:m-30\:m$

$2x=18\:m$

$x=18\:m/2$

$\therefore\boxed{x=9\:m\:is\:the\:breadth}$

$\large\tt\color{green}\underline{\underline{Verification:}}$

See , formula to find perimeter of the rectangle is:

$= 2×(L+B)$

Now , let's find the answer :

$2×(15m+9m)$

$2×24m$

$48m\:is\:the\:perimeter$

So , the answer is also verified.

Answer 2

Question:-

➣

The length of rectangle is 15 metres and its perimeter is 48 metres and breadth is...?

AnSwEr:-

➣

• Given:-

➣ Length = 15 metres

➣ Perimeter = 48 metres

• To Find:-

➣ Breadth = ?

• Formula Used:-

➣ Perimeter of Rectangle = 2×(L+B)

Soln:-

➣ Let the breadth be x

➣ 2×(L+ x) = 48m

➣ 2×(15m+x)=48m

➣ 30m+2x=48m

• Moving x on one side:-

➣ 2x=48-30m

➣ 2x=18m

➣ x = $\frac{18}{2}$

$\therefore{ Therefore{\boxed{\purple{x=9m}}}}$

➣ The breadth of the Rectangle is 9m.

__________________________________________________

• Verification:-

➣ By putting the value of B(breadth) in the Perimeter formula we can verify the Answer.

• Perimeter of the rectangle = 2×(L+B)

➣ 48m = 2×(15m+9m)

➣ 48m = 2×24m

➣ 48m = 48m

➣48m is the perimeter

Hence, Verified ✅
