Question

The perimeter of the rectangle is 60m.if its length is twice its breadth then its area is

Answer 1

2(l+b)=60
l+b=30
Also, l=2b,
2b+b=30
b=10, l=20,
Area=l×b=10×20=200

Answer 2

Answer:area is 200 ${m}^{2}$

Step-by-step explanation:

Perimeter of rectangle =60 m

Let the length be 2x

Let the breath be x

Perimeter of rectangle=2(length+breath)

60=2(2x+x)

60=2×3x

60 =6x

x=10

Now length is equals to 20

breath is equals to 10

Area of rectangle=length×breadth

20×10 =area

200${m}^{2}$ is the required area.
