Question

The length of a rectangular field is 3 times its breadth if the perimeter of the rectangle is 56 m, Find its length and breadth

Answer 1

hi mate here is ur answer

let the breadth of the rectangle be x

so the length is thrice the breadth so length = 3x

the perimeter of the rectangle is given as 56

perimeter of rectangle = 2(l+b)

56= 2 ( 3x+x)

56 = 2 (4x)

56 = 8x

x = 56/8

x = 7

breadth of rectangle is 7

length is 3x so,

length of rectangle = 7  x  3 = 21

length = 21

hope it helps!!!
