Answer 2

Answer:

25 cm.

Step-by-step explanation:

Perimeter of rectangle= 2(l+b)

where l is length and b is breadth.

According to the question,

The perimeter of rectangular table=80cm

And it's breadth = 15 cm.

80=2(l+15)

80=2l+30

80-30=2l

50=2l

l=25 cm.

The length of the rectangular table is 25 cm.
