the perimeter of a rectangle is 40 cm the length is 1 less than twice the width of the rectangle find its length and breadth About the author Kaylee
Step-by-step explanation: Let the breath be x 2(l+b) = 40 cm 2( 2x-1 + x ) = 40 cm 6x – 2 = 40 cm 6x = 42 cm x = 42/6 cm x = 7 cm ∴ The breath is 7 cm, and the length is 13 cm Reply
Step-by-step explanation:
Let the breath be x
2(l+b) = 40 cm
2( 2x-1 + x ) = 40 cm
6x – 2 = 40 cm
6x = 42 cm
x = 42/6 cm
x = 7 cm
∴ The breath is 7 cm, and
the length is 13 cm
