Question

The lenghth of rectangule is twice its breadth if the perimeter is 72 m. Find the lenggth and breadth

Answer 1

Answer:

Step-by-step explanation:

given that l=2b , perimeter=72

perimeter=2(l+b)

2(2b+b)=72

2(3b)=72

6b=72

b=12

l=2b

2(12)=24

Answer 2

Answer:

l=24m,b=12m

Step-by-step explanation:

Let breadth be x

length be 2x

Perimeter of rectangle=2(l+b)=72m

72=2(2x+x)

72=2(3x)

72=6x

x=72/6=12

Therefore,x=breadth(b)=12m

2x=length(l)=24m
