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.
