See lessThe length of a rectangle is three times the breadth. If the minimum perimeter of the rectangle is 160 cm, then
Choice (c) is correct. Let x cm be the breadth of the rectangle. Length of the rectangle = 3x cm and perimeter of the rectangle = 2 ( length + breadth) = 2(3x + x) = 8x cm Given, minimum perimeter = 160 cm 8x ≥ 160 ⇒ x ≥ 20 Hence, breadth ≥ 20 cm.

Choice (c) is correct.
Let x cm be the breadth of the rectangle.
Length of the rectangle = 3x cm
and perimeter of the rectangle = 2 ( length + breadth) = 2(3x + x) = 8x cm
Given, minimum perimeter = 160 cm
8x ≥ 160 ⇒ x ≥ 20
Hence, breadth ≥ 20 cm.
