Let us assume that the shorter side of the rectangle is 4x and the longer side is 3x.
Perimeter of the rectangle = 2 × (length + breadth)
=> 168 = 2 × (4x + 3x)
=> 168 = 2 × 7x
=> 168/14 = x
=> x = 12
Therefore, the shorter side of the rectangle = 4x = 4 × 12 = 48 cm.
Hence, the length of the shortest side is 48 cm.
The sides of a rectangle are in the ratio of 4:3.
The perimeter is 168cm.
What is the length of the shortest side?
