breadth of the
bar​

Answer 1

Answer:

Q.The length of a rectangle is twice of its breadth if its perimeter is 60cm find its length.

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.
