Question

if lenth of rectangle is A and breadth is half of the length, then perimeter of the rectangle​

Answer 1

Given ,

length = A

Breadth = A/2

Perimeter = 2(l+b)

=> 2(A+A/2)

=> 2 × 3A/2

=> 3A

Perimeter = 3A

Answer 2

$\huge\bf { \red A \green N \pink S\blue W \orange E \purple R \green{...}}$

Length of rectangle = A

Breadth of rectangle = A/2

Perimeter of rectangle = 2 ( L + B )

→ 2 ( A + A/2 )

→ 2 ( 3/2A )

→ 6/2A

→ 3A

Perimeter of rectangle is 3A
