Question

The length and breadth of a rectangle are (3a + 2) and (2a - 1). Which of the following represents its perimeter?
A) 2(5a - 1) B) (5a + 1) C) (5a - 1) D) 2(5a + 1)

Answer 1

Hi

Perimeter of A Rectangle =
$2(length + breadth)$

Hence, Perimeter is :
$2(3a + 2 + 2a - 1)$

$= 2(5a + 1)$

Hence, (D) is the Perimeter ✓✓
