Question

the length of a rectangle is 4 time its width if the perimeter of the rectangle is 60 metres find the length and the breadth of the rectangle​

Answer 1

Given :

The length of a rectangle is 4 time its width if the perimeter of the rectangle is 60 m

To find :

• Length and breadth of rectangle

Solution :

• Perimeter of rectangle = 60m

Let the width be x then length be 4x

According to formula of perimeter of rectangle

→ 2(length + breadth) = 60m

→ 2(4x + x) = 60

→ 5x = 60/2

→ 5x = 30

→ x = 6

•°• Width of rectangle = x = 6m

•°• Length of rectangle = 4x = 24m

Focus Zone :

★ 1kilometer = 1000m

★ Distance never be in negative

★ Area of rectangle = length × breadth

Answer 2

Question ::-

The length of a rectangle is 4 time its width if the perimeter of the rectangle is 60 metres find the length and the breadth of the rectangle.

Given ::-

• The length of rectangle = 4 times to it's width.

• Perimeter of rectangle = 60 m

To find ::-

• Find the length of rectangle ?

• Find the breadth of rectangle ?

Solution ::-

Let the breadth be x.

According to question ::-

• Length is 4 times to it's width .

• 4x

_______

• Perimeter of rectangle

• 60 m

_______

Perimeter of rectangle = 2 ( length + breadth)

$➠$ 60 = 2 ( 4x + x )

$➠$ 60 = 2 ( 5x )

$➠$ $\dfrac{60}{2}$ = 5x

$➠$ 30 = 5x

$➠$ x = $\dfrac{30}{5}$

$➠$ x = 6cm.

___________

• Length = 4x = 4 × 6 = 24m

• Breadth = x = 6 cm.

__________

Let's explore more ::-

• Area of rectangle = length × breadth

• 1 km = 1000 m

• 1 m = 100 cm
