Step-by-step explanation:
Answer:
5 units
Step-by-step explanation:
To solve this we can use pythagoras theory:
- a² + b² = c², where c is the diagonal
- 3² + 4² = c²
- 9 + 16 = 25
- c² = 25, so c = √25
- c = 5
Hope this helps!
n ∈ natural even numbers
Step-by-step explanation:
1 + 3 + 5 + 7 + … + (2n-1)
sum of the first n terms :
Sₙ = n/2(a + Uₙ)
Sₙ = n/2(1 + 2n - 1)
Sₙ = n/2(2n)
Sₙ = n²
∴ so, the solution of n is all natural even numbers
