Question

The length of a rectangular plot is thrice its breadth. (3 marks)
If the perimeter of the plot is 144 m, find its length
and breadth.
[Hint: Perimeter of rectangle = 2 x (length + breadth)]

Answer 1

Answer:

length=18,breadth=54

Step-by-step explanation:

let length be x

.: breadth=3x

perimeter of rectangle=2(length+breadth)

144=2(x+3x)

144/2 = 4x

72 = 4x

72/4 =x

18=x

.:length=x=18

breadth=3x=3*18=54
