Question

the length of a rectangular floor is 20m than its width if the perimeter of the floor is 280m what is its length please help​

Answer 1

Answer:

80m

Step-by-step explanation:

Let the width be x.

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

4x=240

x=60

Length=60=20=80

Answer 2

Answer:

let the breadth be xm and length be (x+20)m.

perimeter=280m

perimeter=2(l+b)

280=2(x+x+20)

2x+20=140

2x=120

x=60m

breadth= x=60m

length=x+20=60+20=80m
