Which of the following statements(s) is/are TRUE?
(I) Area of a parallelogram whose base and corresponding altitude are 15 cm and 12 cm, respectively, is 180 cm²
(II) The sum of all the interior angles of a regular octagon is 900°.
Show answer & explanation
Correct answer: C
Explanation
Given:
(I) Base = 15 cm, Height = 12 cm
(II) Regular Octagon
According to the formula:
Area of a parallelogram = Base × Height
Sum of interior angles of a polygon = (n − 2) × 180
Area = 15 × 12 = 180
Therefore, Statement (I) is true.
(II)
n = 8
Sum of interior angles = (8 − 2) × 180 = 1080°
Therefore, Statement (II) is false.
Only (I) is true.
