Answer:
Height of the parallelogram = 37.5 cm
Step-by-step explanation:
As given,
Base of a parallelogram = 75 cm
Height of a parallelogram = 25 cm
As,
we know that
Area = Base × Height
= 75 × 25
= 1875 cm²
As the parallelogram is same
So, Area = Base × Height
⇒1875 = 50 × Height
⇒ Height = = 37.5 cm
So, we get
Height of the parallelogram = 37.5 cm
Option A: is the value of
Explanation:
It is given that the first term is
The common difference is
We need to determine the sum of 25 terms.
The sum of terms of an arithmetic series can be determined using the formula,
Substituting ,
and
Thus, we have,
Simplifying the values, we get,
Subtracting the terms within the bracket, we get,
Multiplying the terms in the numerator, we have,
Dividing, we get,
Thus, the sum of the 25 terms is
Therefore, Option A is the correct answer.
