Answer 1

Answer:

Correct Question

The perimeter of a a rectangle swimming pool is 154 metre its length is 2 metre more than twice its Breadth . What are the Length and the Breadth of the full pool.

To Find:-

The Length and the Breadth of the full pool.

Given:-

Perimeter of the rectangular pool = 154 m.

Length is 2m more than twice it's breadth.

Solution:-

step-by-step explanation:

Let the breadth of the rectangular pool be x .

Now, The length of the rectangular pool is

Now, The length of the rectangular pool is(2x+2)m

We know that perimeter of a rectangle is

= 2 ( length + Breadth )

So,

= 2( 2x + 2 + x )

= 4x + 2 + 2x

= 6x + 4

By the question, we have to do

6x + 4 = 154

6x = 154 - 4 { by transposing 4 to R.H.S }

6x = 150

x = 25.

Required Answer

So,

Breadth = 25 m

Length = 25 × 2 + 2

= 50 + 2

= 52 m

Some Important Concept

Perimeter = 2 ( length × breadth )

Area of triangle = 1/2 × breadth × height

Area of rectangle = width × height

Area of rectangle = width × height
