Question

The perimeter of a rectangle is same as the perimeter of a square of side 15 cm. If length of the
rectangle is 17 cm, find its breadth.
5.​

Answer 1

Answer:

we have perimeter of rectangle = perimeter of square

so 2(l+b) = 4(side)

2(17+b) = 60

17+b = 30

b = 13

Answer 2

Answer:

$\large \mathfrak{ \pink{ \underline{ \underline{ \dag \: Question}}}}$

The perimeter of a rectangle is same as the perimeter of a square of side 15 cm. If length of the rectangle is 17 cm, find its breadth.

$\large \mathfrak{ \blue{ \underline{ \underline{ \dag \: Answer}}}}$

Given :

$Side \: of \: Square \: = 15 cm.$

$Length \: of \: Rectangle \: = 17 cm.$

$Perimeter \: of \: Rectangle \: = \: Perimeter \: of \: Square$

To find :

Breadth of the rectangle.

Solⁿ :

$Perimeter \: of \: Square = 4 \times S$

Perimeter of this square

$= >4 \times 15 = 60 \: cm.$

Now,

$Perimeter \: of \: Rectangle = 2\times(l + b)$

Let the breadth of the rectangle be b.

$= > 2 \times (17 + b) = 60 \: cm$

$= > 34 + 2b = 60 \: cm$

$= > 2b = 60 - 34$

$= > b = \frac{26}{2}$

$= > b = 13 \: cm$

∴ Breadth of the rectangle is 13 cm✅.
