Question

the length of a rectangular four times its breadth. if perimeter of the field is 900metre find dind its length and breadth

Answer 1

Length = 4(breadth)

Let the breadth be X

length becomes 4X

perimeter of the field = 900 meters

2( length + breadth) = 900

2( 4X+X) = 900

5X = 450

X = Breadth = 90 Cms

Length = 4X = 4*90 = 360cms
