Question

The perimeter of a rectangular swimming pool is 154m.Its length is 2m more than twice its breadth .what are the length and the breadth of the pool

please tell me am having exam tomorrow ​

Answer 1

Answer:

Let the breadth be x

Length be 2x +2

perimeter= 2(x+2x+2)

= 2(3x+2)

= 6x+4

6x+4= 154

6x=154-4

6x=150

x=150/6

x= 25

length=52m

breadth=25m

Answer 2

Answer:

${\huge{\pink{\underline{\underline{GiVeN:}}}}}$

• Perimeter of pool=154m
• Length =twice the breadth+2
• Breadth=1/2of length-2

${\huge{\pink{\underline{\underline{To\ Find:}}}}}$

• Length=???
• Breadth=???

${\huge{\pink{\underline{\underline{SoLuTiOn:}}}}}$

Let the breadth be x

than the length be 2x+2

According to question,

Perimeter of rectangular pool=154m

=>(2[l+b])=154m

=>2([2x+2]+x)=154m

=>2(3x+2)=154m

=>6x+4=154m

=>6x=154-4

=>x=150÷6

Hence,x=25.

So,breadth=x=25m

Length=2x+2=2×25+2=50+2=52m
