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

Answer:

2(l+b)= perimeter

2(x+20+x)=280

2(2x+20)=280

4x+40=280

4x=240

x=240/4

x=60m^2 Answer

Answer 2

Breadth be x
Length = x + 20

2(2x + 20) = 280m
4x + 80 = 280m
4x = 200m
x = 50m

Breadth = 50
Length = 70
