Question

The perimeter of a rectangular swimming pool is 188m. It's length is 4m more than twice its breadth.find the length and breadth.

Answer 1

Given :

• he perimeter of a rectangular swimming pool is 188m.
• It's length is 4m more than twice its breadth.

To find :

• The length and breadth of the rectangular swimming pool =?

Formula Used :

• Perimeter of the rectangle = 2( length + breadth)

Step-by-step explanation :

Let, the breadth of the rectangular swimming pool be, x.

Then, the length of the rectangular swimming pool be, 2x + 4.

It is Given that,

The perimeter of a rectangular swimming pool is 188m.

As We know that,

Perimeter of the rectangle = 2(length + breadth)

Substituting the values in the above formula, we get,

188 = 2(x + 2x + 4)

188 = 2(3x + 4)

188 = 6x + 8

6x + 8 = 188

6x = 188 - 8

6x = 180

x = 180/6

x = 30.

Therefore, We got the value of, x = 30 m.

Hence, the breadth of the rectangular swimming pool, x = 30 m.

Answer 2

★ Question

The perimeter of a rectangular swimming pool is 188m. It's length is 4m more than twice its breadth.find the length and breadth

★ Given

• Perimeter of rectangle = 188
• length is 4m more than twice of breadth

★ To Find

• length = ?
• breadth = ?

★ Solution

• let length = x
• breadth = 2x+4

perimeter of rectangle = 2(l+b

where , l = length , b = breadth

$→188= 2(x+2x+4)\\\sf→ 188= 2(3x+4)\\\sf→ 188=6x+8\\\sf→ 188-8=6x\\\sf→ 180=6x\\\sf→ x=\frac{180}{6} \\\sf→x= 30$

★ Hence,

• Length = x = 30m
• Breadth = 2x+4 = 2×18+4 , 36+4=40m
