the perimeter of a rectangular swimming pool is 154 m . Its length is 2m more than twice its breadth . what are the length and the breadth of the pool .
Answers
perimeter of rectangle pool=154m.
l=2b
b=b.
perimeter =154
2(l+b)=154.
2(2b+b)=154
6b=154
b=154/6
b=25.8m.
l=2b=2*25.8=51.6m

Answer:
BREADTH =25M AND LENGTH = 25× 2 + 2 = 52 M
Step-by-step explanation:
Let the breadth of rectangular swimming pool be x metres.
Let the breadth of rectangular swimming pool be x metres. Then, its length =(2x+2) metres.
Let the breadth of rectangular swimming pool be x metres. Then, its length =(2x+2) metres.We know that the Perimeter of a rectangle =2(Length+Breadth)
Let the breadth of rectangular swimming pool be x metres. Then, its length =(2x+2) metres.We know that the Perimeter of a rectangle =2(Length+Breadth)=2(2x+2+x)=6x+4
Let the breadth of rectangular swimming pool be x metres. Then, its length =(2x+2) metres.We know that the Perimeter of a rectangle =2(Length+Breadth)=2(2x+2+x)=6x+4According to the given condition, we have
6x+4=154
6x+4=154⇒6x=154−4 ..[By transposing 4 to RHS]
6x+4=154⇒6x=154−4 ..[By transposing 4 to RHS]⇒6x=150
6x+4=154⇒6x=154−4 ..[By transposing 4 to RHS]⇒6x=150⇒6x=6150 ...[Dividing both sides by 6]
6x+4=154⇒6x=154−4 ..[By transposing 4 to RHS]⇒6x=150⇒6x=6150 ...[Dividing both sides by 6]⇒x=25
6x+4=154⇒6x=154−4 ..[By transposing 4 to RHS]⇒6x=150⇒6x=6150 ...[Dividing both sides by 6]⇒x=25 Thus, breadth =25 m and length =25×2+2=52 m
