Question

The perimeter of a rectangular room is 246 m. If the length is 3 m more than thrice its breadth. Find the length and breadth of the pool.​

Answer 1

Step-by-step explanation:

Answer:-

Given that:-

• Perimeter = 246 m
• Length is 3 metre more than 3x its breadth.

Concept:-

Perimeter and Area

Let's Do!

• Let us assume breadth as x.
• So, length is 3+3x

According to the question:-

Perimeter = 2(L+B)

• L is length
• B is breadth

$246 = 2(3 + 3x + x)$

$246 = 2(3 + 4x)$

$246 = 6 + 8x$

$246 - 6 = 8x$

$240 = 8x$

$x = \dfrac{240}{8}$

$x = 30 \: m$

• So, breadth is 30m.
• Length is 3 + 2×30
• So, length is 63 metre.

Answer 2

$good \: afternoon \\ here \: is \: your \: answer \: check \: it \:$

Given:-

Perimeter = 246 m

Length is 3 metre more than 2x its breadth.

Solution

Let us assume breadth as x.

So, length is 3+2x

According to the question:-

Perimeter = 2(L+B)

L is length

B is breadth

=246=2(3+2x+x)

=246=2(3+3x)

=246=6+6x

=246-6=6x

=240=6x

x=240÷6

x=80m

BREADTH= 80m

LENGTH=3+2x

=3+2(80)

=3+160

=163 m
