and breadth.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

let the rectangle of a breadth is x

then, length is 2x

A.T.Q.

perimeter of rectangle = 2(l+b)

78cm = 2(2x+x)

78cm = 2×3x

78 = 6x

78/6 = x

x = 13cm

2x = 2×13 = 26cm

LENGTH IS 26cm

BREADTH IS 13cm
