Let the breadth of the pool be x m. Then, the length of the pool = (2x+2)m Perimeter = 2(l+b) ⇒ 154 = 2(2x+2+x) ⇒ 154/2 = 2(2x+2+x)/2 [Dividing both sides by 2] ⇒ 77=3x+2 ⇒ 77-2=3x+2-2 [Subtracting 2 from both sides] ⇒ 75=3x ⇒ 75/3=3x/3 [Dividing both sides by 3] ⇒ 25=x ⇒ x=25 Length of the pool= 2xRead more
Let the breadth of the pool be x m.
Then, the length of the pool = (2x+2)m
Perimeter = 2(l+b)
⇒ 154 = 2(2x+2+x)
⇒ 154/2 = 2(2x+2+x)/2 [Dividing both sides by 2]
⇒ 77=3x+2
⇒ 77-2=3x+2-2 [Subtracting 2 from both sides]
⇒ 75=3x
⇒ 75/3=3x/3 [Dividing both sides by 3]
⇒ 25=x ⇒ x=25
Length of the pool= 2x+2=2×25+2=50+2=52 m, Breadth of the pool=25m Hence, the length of the pool is 52 m and breadth is 25 m.
Let the number be x. According to the question, 1/2(x-1/2)=1/8 ⇒ 2x1/2(x-1/2)=1/8x2 [Multiplying both sides by 2] ⇒ x-1/2=1/4 ⇒ x-1/2+1/2=1/4+1/2 [Adding both sides1/2] ⇒ x=1+2/4 ⇒ x=3/4 Hence, the required number is 3/4 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-8Read more
Let the number be x.
According to the question, 1/2(x-1/2)=1/8
⇒ 2×1/2(x-1/2)=1/8×2 [Multiplying both sides by 2]
⇒ x-1/2=1/4

⇒ x=1+2/4 ⇒ x=3/4
Hence, the required number is 3/4
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 breadth?
Let the breadth of the pool be x m. Then, the length of the pool = (2x+2)m Perimeter = 2(l+b) ⇒ 154 = 2(2x+2+x) ⇒ 154/2 = 2(2x+2+x)/2 [Dividing both sides by 2] ⇒ 77=3x+2 ⇒ 77-2=3x+2-2 [Subtracting 2 from both sides] ⇒ 75=3x ⇒ 75/3=3x/3 [Dividing both sides by 3] ⇒ 25=x ⇒ x=25 Length of the pool= 2xRead more

If you subtract ½ from a number and multiply the result by ½, you got 1/8. What is the number?
Let the number be x. According to the question, 1/2(x-1/2)=1/8 ⇒ 2x1/2(x-1/2)=1/8x2 [Multiplying both sides by 2] ⇒ x-1/2=1/4 ⇒ x-1/2+1/2=1/4+1/2 [Adding both sides1/2] ⇒ x=1+2/4 ⇒ x=3/4 Hence, the required number is 3/4 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-8Read more
