Question

the length of a rectangular floor is 20 metres more than its breadth if the perimeter of the floor is 280 metres what is its length ​

Answer 1

let lenth = x + 20

let breath = x

now perimeter =)

x+x+x+20+x+20=280

4x=280-(20+20)

4x=280-40

x=240/4

x= 60

breath = 60 meters

lenth =x+20

=) 60+20

= 80 meters

ANSWER -) lenth is 80 meters and breath is 60 meters
