Question

Question => The perimeter of a rectangular swimming pool is 154 m. its length is 2 m more than twice its breadth. what are the length and the breadth of the pool?​

Answer 1

Answer:

Breadth=25

Length=52

Step-by-step explaination:-

Let breadth be x

then length = 2(x+2)

Perimeter = 2(l+b)

=2(2x+2+x)

=6x+4

6x+4=154

6x=154-4=150

6x=150

x=150/6= 25

Breadth=25

Length=2(x+2)

=2(25+2)

=2×27

=52

Hence

Breadth=25

Length=52

Answer 2

Answer:

Given :

• The perimeter of a rectangular swimming pool is 154 m
• Its length is 2 m more than twice its breadth

To find :

• The length and breadth of the pool

Solution :

• Let the breadth of rectangular swimming pool be x metres.
• Then, its length = (2x+2) metres.

We know that,

Perimeter of a rectangle: = 2 (Length + Breadth)

→ 154=2(2+2x+x)

→ 154 = 2(2+3x)

→ 154=4+6x

→ 154-4-6x

→150=6x

= x= 150/6= 25 cm

Therefore :

• Breadth of swimming pool, x= 25cm
• length of swimming pool, (2 + 2x) = 2 +50 = 52cm
