Question

find the length of a rectangle whose perimeter is 52cm and breadth is 12cm​

Answer 1

Answer:

Given :-

• A rectangle whose perimeter is 52 cm and breadth is 12 cm.

To Find :-

• What is the length of a rectangle.

Formula Used :-

$\clubsuit$ Perimeter Of Rectangle Formula :

$\footnotesize \bigstar \: \: \sf\boxed{\bold{Perimeter_{(Rectangle)} =\: 2(Length + Breadth)}}\: \: \: \bigstar$

Solution :-

Let,

$\mapsto \bf Length_{(Rectangle)} =\: x\: cm$

Given :

• Perimeter of Rectangle = 52 cm
• Breadth = 12 cm

According to the question by using the formula we get,

$\footnotesize \implies \bf Perimeter_{(Rectangle)} =\: 2(Length + Breadth)$

$\implies \sf 52 =\: 2(x + 12)$

$\implies \sf \dfrac{52}{2} =\: x + 12$

$\implies \sf 26 =\: x + 12$

$\implies \sf 26 - 12 =\: x$

$\implies \sf 14 =\: x$

$\implies \sf\bold{x =\: 14}$

Hence, the required length of a rectangle is :

$\dag$ Length Of Rectangle :

$\dashrightarrow \sf Length_{(Rectangle)} =\: x\: cm$

$\dashrightarrow \sf\bold{\underline{Length_{(Rectangle)} =\: 14\: cm}}$

$\therefore$ The length of a rectangle is 14 cm .

Answer 2

Answer:

perimeter of rectangle = 52cm

breadth of rectangle = 12cm

perimeter = 2(l+b)

52 = 2 (l+12)

52/2= l+12

26-12 = l

14 = l

length = 14 cm
