Question

the breadth of a rectangular hall is 8 metres less than its length.if the perimeter of the hall is 72 metres ,then find the length and breadth of the hall.

Answer 1

let the length of the rectangular room be x
than the breadth
ATQ
b = x - 8
the perimeter given 72m
perimeter of a rectangle = 2(l + b)
=72 = 2 ( x + (x - 8 ) )
= 36 = 2x - 8
= 36+ 8 = 2x
44 = 2x
x = 44/2
x = 22
length = 22m
breadth = 22-8 = 14m
