Question

Arav sits in an office where the perimeter of the rectangular floor of the room is 72m. the length of the floor is 5 times it's breadth. find its dimensions
​

Answer 1

Perimeter= 72 m

let the breadth (B)= x

ATQ,

length (L)=5x

PERIMETER OF RECTANGLE = 2(L + B)

72= 2 ( 5x + x)

72= 2(6x)

72= 12x

x=72/12

x=6

THEREFORE BREADTH=x=6m

LENGTH=5x = 6 × 5= 30 m

HOPE THIS HELPS YOU :)
