The length of a rectangle is 3 times its breadth if the perimeter of the rectangle is 26 cm find the length of the rectangle

Let the breadth of the rectangle be x cm.

Then, the length of the rectangle is 3 times the breadth, i.e., 3x cm.

Perimeter of rectangle = 2(length + breadth)
26 = 2(3x + x)
26 = 2(4x)
26 = 8x
x = 26/8
x= 3.25 cm

Therefore, breadth of the rectangle is 3.25 cm and its length is 3(3.25) = 9.75 cm.
