Answer:
The answer for the consecutive natural numbers question is 16 17 18
Answer:
2. Ans: 154 m.
3. Ans: 16, 17, 18.
4. Ans: 20 root 30.
Step-by-step explanation:
2. Ans: The length is 2 m more than twice its breadth. So, the length of the pool is (2x+2). The perimeter of the pool is 154 m.
3. Ans: The sum of three consecutive numbers is 51. What are the numbers?
Three consecutive numbers: x,x+1 and x+2.
The sum of these numbers is 51 . So,
x+(x+1)+(x+2)=51
x+x+1+x+2=51
3x+3=51
3x=51−3
3x=48
x=483
x=16
So, the numbers are 16,17 and 18.
4. Ans: Given,
Let smaller side = a --------------- (i)
one side = a + 4 --------------- (ii)
third side = 2a - 6 --------------- (iii)
On solving (i),(ii),(iii) we get
= a + a + 4 + 2a - 6 =50
= 4a - 2 = 50
a = 13
Substituting a value in (i),(ii),(iii)
smaller side = 13
one side = 17
third side = 20
Perimeter = 20 + 17 + 13/2
= 50/2
= 25
Area = s(s-a)(s-b)(s-c)^1/2
= (25(25-13)(25-17)(25-20))^1/2
= 20(30)^1/2
= 20 root 30.
