The perimeter of a rectangle is 50 cm. The lenght is 2x cm. Determine the breadth in terms of x
Let the length of the rectangle be 2x cm and the breadth be y cm.
Perimeter of a rectangle = 2(length + breadth)
Given, perimeter = 50 cm
2(2x + y) = 50
4x + 2y = 50
2y = 50 - 4x
y = (50 - 4x)/2
y = 25 - 2x
Therefore, the breadth of the rectangle in terms of x is 25 - 2x cm.
