Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
Divide both sides by 8.
Now,
Therefore, the length of the parallelogram is 24 cm.
Answer:
= 4n - 13
Step-by-step explanation:
There is a common difference d between consecutive terms , that is
d = - 5 - (- 9) = - 1 - (- 5) = 3 - 1 = 7 - 3 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 4, thus
= - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
Answer:
a)
Step-by-step explanation:
is approximately 17.8
17² = 289
18² = 324
315 is between 289 and 324
