Answer 1

Hey mate :)

☆Perimeter of a rectangle☆

• 120cm

☆Ratio of length and breadth☆

• 2 : 1

Let length = 2x

Let breadth = x

☆formula to find perimeter of rect.☆

• 2 ( length + breadth )

=》2 ( L + B ) = 120cm

=》2 ( 2x + x ) = 120cm

=》2 ( 3x ) = 120cm

=》6x = 120cm

=》x = 120 / 6

=》 x = 20cm

___________________××××__________

• Length = 2x ......... 2 × 20 = 40cm
• Breadth = x............ 20cm
