Answer 2

Correct question!!

The length of a rectangle is twice its breadth if it's perimeter is 60cm find the length and the breadth.

Solution!!

Perimeter = 60 cm

Let the breadth be x.

Length = 2x

Perimeter = 2(Length + Breadth)

60 cm = 2(2x + x)

30 cm = 2x + x

30 cm = 3x

x = 30 cm ÷ 3

x = 10 cm

2x = 2 × 10 cm = 20 cm

Hence, the length and breadth of the rectangle are 20 cm and 10 cm, respectively.
