Question

the length of a rectangular field is two times its breadth if the perimeter of 72 find its length and breadth​

Answer 1

Answer:

Perimeter is equal to 2(l+b)

Wkt, l=2b

Then 2(2b+b)= 72

2(3b)= 72

6b=72

B=12cm

Then l=24 cm

Answer 2

Answer:

Length =12×2=24m

Breadth = 12m

Step-by-step explanation:

Perimeter=72m

Let the breadth be x

Let the length be 2x

Perimeter=2(l+b)

72=2(2x+x)

72=2(3x)

72=6x

x=72÷6

x=12m
