Question

8. The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the
length and the breadth of the rectangle.​

Answer 1

Answer:

Let the breadth of the field = x cm ∴ its length = 2x and, its perimeter = 2 x (length + breadth) = 2 x (2x + x) = 2(3x) = 6x cm Perimeter = 60 cm ⇒ 60 cm = 6x cm ⇒ x = 60/6 = 10 cm ∴Breadth = x = 10 cm Length = 2x = 2 x 10 = 20 cm
