Question

Find the length of the rectangle with the rectangle whose perimetre 14 cm and breaths 2cm

Answer 1

Answer:

The length of the given rectangle is 5 centimeter.

Step-by-step explanation:

The perimeter of a shape is the sum of the measurements of its sides. For a rectangle  of length $l$ and breadth $b$, the perimeter is,

$Perimeter = 2(l+b)$

It has given that the perimeter of the rectangle is 14 cm and the breadth is 2cm. That is

$Perimeter = 14 \ cm\\Breadth = 2 \ cm$

Hence we have

$\implies 14= 2(l+2)\\\\\implies l+2 =\dfrac{14}{2} \\\\\implies l+2=7\\\\\implies l=7-2=5$

Thus the length of the rectangle is 5 cm.

Answer 2

Given :-

Perimeter of the rectangle = 14 cm

Breadth of the rectangle = 2 cm

To Find :-

Length of the rectangle = ?

Formula Used Here :-

Perimeter of rectangle = 2(l + b)

Solution Start :-

Perimeter of rectangle = 2(l + b)

➲ 14 cm = 2(l + 2)

➲ 14 cm = 2l + 4

➲ 14 - 4 = 2l

➲10 = 2l

➲ $\frac{10}{2} = l$

➙ 5 cm = l

Hence, Length = 5 cm
