X+4
2x+2​

Answer 1

Answer:

Step-by-step explanation:

The perimeter of a rectangle is given by the formula 2*L + 2*B, where L is the length and B is the breadth.

Since L = 2*B, we can substitute this in the above equation to find the perimeter.

Thus, 2*2*B + 2*B = perimeter. Given perimeter is 78, we get

78 = 4*B + 2*B = 6*B.

Or B = 78/6 = 13.

And length L = 2*13 = 26cm.

Thus, the Length = 26cm and Breadth = 13cm.
